Guys,
Another day, another observation. When you plug in the headphones, do you guys hear a hissing/static/white noise for a couple of seconds initially. I am able to reproduce this every time I plug in my headphones (tried three different sets). I am not too bothered by it because the noise dies after 2-3 seconds. I also witness the same behavior when I pause a song.
I guess I am raising the topic here because am not sure if this is common across all WP7 devices (thereby making this a WP7 issue), if it is only my phone, or if it is common across all Venue Pros.
Thanks for any input.

I get the same noise, but mine is constant. Whenever a sound plays, the white noise/hissing in the background comes up and continues for 5-10 seconds after the sound is played and then goes out. Then when another sound happens, it does it again.
It almost makes using headphones unbearable.
I've tried multiple sets of headphones too, it does it on them all.
I think it may have something to do with the curved top of the phone and the fact that the plug doesn't go all the way into the device.
Anybody else have a similar experience?

I don't think it's that - if the curved surface was the culprit, the sound wouldn't vanish after a few seconds. It almost seems like a software issue.
Thanks for confirming the behavior!
I only hear the hissing sound for a few seconds after plugging it in to the jack...
Hearing a hissing on most smartphones is pretty common, in my experience. The better quality earphones you use the more you will notice it. The Nexus One did, the Venue Pro does, my N95 did a bit.
People I've called with the built in headphones/mic say the noise levels are so extreme they are unusable. Hopefully the free Bluetooth headset we're all getting will fix that issue...
Hello!
This is normal when companies use cheap DACs and amps for sound replication. The DAC turns on when you play sounds, and turns off when there's a period of no sound. If it's a cheap system, there's a noticeable base sound/noise that is added to your signal.
When you have music playing, that, of course, is drowned out by the music. Thus, you won't hear it unless you have really soft music, say, a few bars rest in your classical album or something.
The problem also is more noticeable with low impedance earphones (IEMs, for example).
A possible, easy way to fix this is to use an inline resistor/impedance cable on your headphones, since typically this noise does not vary with volume (in my experience). Then, you bump up the volume on your device... if it's powerful enough to do it. Otherwise, you'll have to inline resistor, a clean-sounding portable amplifier (powered by additional), and then your headphones. It gets pretty bulky...
Alternatively! Separate your music player and your phone. Unfortunately, the DVP has such a nice Zune interface. And still, with cheap music players you can hear the hiss if you're careful. I can hear this on iPods with my earphones still...
Sorry to hear about this! I was hoping that the sound quality would be decent. I might try to get an HD7 instead now...
Cheers!

Just to let you know, the HD7 does not have the hissing/static that the DVP does. I've tried the HD7, Samsung Focus and DVP and HD7 had the best sound quality in my opinion. The Focus sounds muffled compared to both HD7 and DVP.
I've got the same hissing noise on mine, but I think it's an issue with a crappy DAC as it's only there when there is sound. I was hoping to replace my Zune HD but there's no way that's gonna happen with this noise - it's AWFUL!
I'm really thinking about moving to a Samsung Focus. I loved this phone when I first got it, but over time I just uncover more and more I don't like.

Very true. Almost every phone I've used has this. It's more noticeable on some phones than others but it's nothing unique to the DVP.
Bringing this back to the top, I've observed something on my new model, though I could have sworn the one I sent back for a refund did not have this problem...and it only occurs with earbuds, and not ear phones (I have a big pair of medium to high quality full-size Creative earphones, the buzzing is not audible at all with them.
Since this phone seems reasonably crash-free, I'm reluctant to press Dell for a replacement, especially if, viola, all the DVPs have this problem. Mine seems particularly loud, but that may be a combination of the Zune Premium earbuds I'm using and other factors. As others said, it vanishes briefly if you pause a song (like the sound output is switching off to save electricity or whatever) but resumes immediately. I might be better off just going through various earphones and finding a brand that's of at least the quality of my current earbuds but minimizes the effect.
EDIT: Additionally, lowering the volume simply makes it much more noticeable.
Here's my issue, hooking up the phone thru the headphone jack to the aux of my benz the volume level is extremely low. I have the volume on phone all the way up. I have to turn it up extremely loud on the car volume to hear it. Is there like a child protection volume setting or? Didn't have this issue with the gnex
Thanks for any help...

Hi,
This is the same for me Anyone got a solution?
Pandora is much quieter than Google Play if you're using one or the other. I find the volume on mine to be on par with my MP3 player so I am satisfied. If you haven't run an aux into your car before you may be just unaware of how 'loud' you have to make it. My car stereo has been to turned up to 45 to hear it while driving, but I listen to the FM radio on like 22.
Nothing much else I can say about this sorry.
You are correct. Its much much lower. My n4 on my car stereo is at like 30 compared to my wife's iPhone at 20. Through Bluetooth its a bit more normal.
Sent from my Nexus 4 using xda premium
I actually find my N4's headphone jack to be a bit louder than my LG G2x's; I have to turn down the speakers from where I had been setting them. (Both require a higher volume than the radio or a CD, though.)
Yea I can't even listen to music without hearing other peoples conversation on the train, Stock Android Volume has always been Low what the heck is Google smoking , the iPhone has great volume levels, I know the N4 3.5mm jack is more than capable
Had the GSM Galaxy Nexus before the N4. In my car, the volume goes from 0-40, 40 being max. On my GN I had the volume from 15 to 25, with 25 being incredibly loud. Anything above that would probably make your ears bleed.
On my N4 with the volume all of the way up and the EQ off (loudest setting) I have to turn the volume up to 40 to hear it at all. I'd say my GN at this volume level would mean my car was on 10, whereas with my N4 is has to be at 40.
The volume is MASSIVELY lower - basically unusably so. I've warrantied out my current N4 in hopes that this is a hardware problem, but after seeing threads like this, I'm beginning to wonder if it's just ridiculously low on purpose.
I don't notice it on headphones/car aux in, I do notice it on a cheap set of external speakers...I haven't found a fix.
any of you tried the volume+ app from the store? I used it on my Sony xperia and it did the trick....

Problem solved through Bluetooth Audio: http://www.amazon.com/GOgroove-BlueGate-Wireless-Bluetooth-Headphones/dp/B00727FE5U/
my headphone goes in crooked.
Yeah.
I tried my bluetooth adapter and, while it's slightly louder, it's still not really that loud. Why do manufacturers choose to make the volume out on phones SOOOO quiet?
Also, Bluetooth audio (A2DP) always sounds so bad to me. I'd much rather have a real, physical connection.
This just seems to be what you get with Android phones. They dont get it. At 100% volume it should be as loud as the radio or CD, except its like 30% lower. My iPod touch and regular ipod were just as loud as the radio and I didnt need to adjust the volume when switching between sources, on my Android stuff I have to crank the stereo volume to unsafe levels and then hope to god I remember to turn it down before switching to the radio. If Im riding on a loud road I have to turn the volume up to like 80% to hear it, that would blow out my speakers if I switched to radio at that volume.
Android makers simply dont understand that AUX needs a pure audio signal at native db, they design the phones for headphone use and have probably never even heard of AUX.

Low earphone volume - Solved !
My friend who is an audio engineer, measured the audio output from nexus 4.
This is what he recommended.
Use a earphone with 16 ohm impedence. (Most commercial phones are 30 ohm).
The sensitivity of the earphone must be 108 dB/mW or higher. Higher the better.
Sensitivity measures the efficiency of conversion of electrical enery into sound.
Based on this, I bought a JVC HA-F150-B. Now audio volume is practically doubled.
You can buy one at ebay for cheap prices.
i have the same problem hooking up my nexus to my car stereo through aux. at first i thought it was just the songza app, but i had no issues with it on my gnex. its to the point where its so low i had to crank my volume on phone and car stereo all the way up and it was still not even as loud as say a cd at half the volume. tried volume + which i was using on my gnex but it doesnt seem to work with my nexus 4. its so annoying .
I bought a Fiio E6 headphone amplifier and called it a day. Problem solved for me at least.
It's not a problem with the phone, it's a problem with the car receiver expecting higher voltage.
Go through the receiver manual and find out if there is a way to adjust the input voltage.
Bump.
I'm facing exactly the same. I'm coming from a cheap Huawei phone that sufferered the same problem (extremely low output, though not as clean) but before that I was using a tiny Samsung Galaxy 5 which cost £30 new and had PERFECT audio/levels on all roms.
I do most of my listening via Tunein which doesn't have any kind of built in amp which can help. I have to crank the volume to max (50 on my Blaupunkt unit) to hear it at an acceptable level, and often that isn't enough. I use radio traffic reports but god help me and the cars around me if they come in while the N4 is hooked up, it'd be deafening!
Surely this can be fixed? I understand the need for safe volumes but there's nothing safe about having to crank everything to max only to have your eardrums popped when you go to listen to the radio.
Very frustrating!!
I just started playing a few games on this Nexus 7, and I turned the volume down to the lowest setting because it is late at night and other people in my house are sleeping. I immediately noticed a soft but very audible static buzz coming from the speakers... about the same volume as the audio itself. I held my ear up to the hardware and confirmed it is both top and bottom speakers.
Anybody else experience this?
copyists sorpeno
I didn't notice at first. Noticed this morning with audio low as well.
I'd like to know if anyone else has this too. Kinda wanna know if its hardware since I purchased at best buy and only have 2 weeks to return.
Yup, I was going to report this too, but since it only occurs at minimal volume I didn't bother. I lost my good headphones so I can test the audio jack. Does it happen to you with them on too?
Btw- if this the trade off with the fantastic (for tablet speakers) surround sound I'll take it. Watch the test video on the Play Videos app.
Sent from my Nexus 7
I don't hear it. on mine. But My hearing is horked.
It's because the Nexus 7 uses a crappy digital volume control that simply reduces the volume of the digital waveform before it hits the DAC, instead of having a real analog volume control -an op-amp that adjusts the volume of the signal before it hits the headphone/speaker amplifier.
What you're hearing is quantization noise as at the lowest volume the audio uses only 2-4 bits of dynamic range instead of the full 16 (or 24, dunno what DAC is in this thing). It's the same as the bit-crushing effect you hear in some dubstep and other electronic music that degrades the audio into a robotic crunchy mess, only here it's not on purpose, it's just cheap design.
There is nothing you can do about it.
I've also noticed this (at first I was like, WTF? Is it raining in my game?). If what was said above is true, that makes me sad that nothing can be done about it.

I'm a professional audio engineer, I know exactly how these things work. Most cheap devices do volume controls that way, because adding a dedicated op-amp for analog volume control increases costs of the device, and the Nexus 7 is a budget device.
It does happen on mine, too, in every app that plays sound.
I love when pros come in here and give the technical explanation haha hats off to you, sir!

As the others have said, thanks for the explanation. Nice to hear from somebody who understands it, and if the problem is present in all units that actually makes me feel better since I don't have to worry about returning my otherwise perfect unit.
Question though, how come I don't hear the static when using headphones, even on the lowest volume settings where I hear the static from the built-in speakers? That makes me think it's related to the speakers and not the audio hardware... but you obviously know more than me on this.

Yeah, funny thing is the first game I played was Bad Piggies on some levels with an ocean tide moving back and forth at the bottom of the screen. I thought the static was the tide sounds... until I heard it in another game too.

It only happens at the absolute lowest volume setting... i.e. one notch up from muted. It sort of happens at the next notch up too, but is most noticeable at the quietest setting, and you need to be in a quiet room. I only noticed because I was using the device in a small echoey mostly tile room (you can probably guess where) and because of the room having such acoustics I put the device on the lowest setting just above mute.
Had something like this on my original nexus 7
Except it happened regardless of the volume setting. Wasn't that audible- had to put my ear against the speaker to really hear it, but it did interfere with other devices, such as my radio, or keyboard with a head phone jack. It would make a sound like a quick DUH-DUH-DUH-DUH-DUH-DUH...DUH-DUH-DUH-DUH-DUH-DUH. My nexus 4 can sometimes cause static interference with other devices, too. Haven't gotten the new nexus 7 so I cannot say whether or not my new one has this issue
Well.. mine's not only happening at the lowest volume notch. If I put it to my ear (never actually going to do this for normal use) it's there at every volume level, just hard to hear once whatever I'm playing gets loud enough. The display unit at a local best buy does the same. I can hear it in a quiet room at the first couple notches (normal use), which is annoying. Also, since someone asked - No it doesn't happen through headphones.

My pleasure! There's tons of FUD on XDA about many things, so I try to contribute on stuff I know well to reduce that.
Without looking at the schematics of the thing I can only guess:
The speaker amplifier is probably just a simple design that outputs 100% power all the time, so you have to control the volume of the signal that enters it, whereas the headphone amp probably has an integrated analog volume control.
A volume control is much easier (read: cheaper) to do in an integrated chip with low power signals (headphone out) than higher power (speaker out), and again, cheaper was the way to go with the Nexus 7.
Hence, there are two separate outputs from the audio chip - one that feeds the speaker amplifier and uses the bit-crushing digital volume control, the other outputs full-scale audio to the headphone amplifier which controls the volume in analog.

No, this is how the hardware is designed.
Noticed this too from the speakers regardless of volume, and regardless of what is playing audio. It's a high pitched squeal to my ears which I can't stand. I've thrown out computer power supplies and video cards that have made similar(obviously, louder) noises.
Was hoping it could be something improved in software, but I guess not. Time to sell this.
http://youtu.be/c9aQnuOrTY8
Recorded what it sounds like at lower volumes with a small condenser mic next to it. Let me know if that's similar to what you guys are hearing too.
<<SOLVED>> The moto G Opamp is not very efficient. It struggles to go down to 2Ohm stable. This means average earbud type headphones rated at 16Ohms. will have hiss and other artifacts. Higher impedance headphones. 40-70Ohms have much better sq. Much above 70Ohms and I suspect the Moto G won't be powerful enough to drive them.... so, that's the sweet spot!
Hey,
Since I updated to kitkta4.4.2 I notice there is a significant background hiss listening with headphones.
As soon as you use an app that activates the audio jack the hiss kicks in, it is constant, not volume dependent. If you turn the volume down to zero, but the app keeps the sound output active the hiss remains.
when the app is closed, the hiss abruptly stops (presumably when the sound API deactivates the inbuilt opamp to save battery)
I'm about 90% sure this wasn't present under 4.3 or was far less noticeable.
I'm not being picky either, this is bad enough that it would make using the phone as a walkman at a low or moderate volume unpleasant. From experience I'd estimate the hiss at approx -20dB.. this is similar to the hiss you would hear from your average desktop PC fan at idle under your desk..
can anyone test this too, on 4.3 and 4.4.2?
Oh, and use earbud headphones or good closed cup ones. Open phones, unless you are somewhere very quiet won't give a good idea of the hiss..
thanks
Can confirm this on 4.4.2, too bad I didn't see your post before updating, as I don't really remember how it was on 4.3 :/
You don't actually have to use earphones, it's noticeable through the speaker, too (well I'm in my room alone and I put my ear close to it). However, I wouldn't say it's very significant - when using earphones I can hear it when muted, on the 1st bar after mute; on the 2nd you can't really say if you hear it or is it your imagination; and on the 3rd bar it's unnoticeable.
I can't notice any hiss in 4.3, even if I use a headphone amp. No clicking sounds either when the opamp turns on.

this is what I was worried about. I didnt notice any hiss before either, and I had it connected to a car stereo so would amplify the issue (if it was there).
maybe something did change in the audio settings/drivers then. I have already tried dissablying all the dsp stuff with no luck, still the hiss and click when the opamp switches on/off.
Maybe it was there before though, and it's bad luck with the phone, rather than the OS version.
I have got UK Retail 4.4.2 and I have tried to replicate this. I have tried YouTube, Spotify Play Music and TuneIn. I do not experience a hiss!

Under 4.3 to save battery I disabled apps I wasn't using, including the Audio Effects app, and google play. When you disable them it forces you to 'uninstall updates' which I didnt realise at the time, but I think may have been specific to the moto g, as you cannot redownload them from playstore, or update them.
Would someone be so kind as to upload the FULL apk of their google play and and Sound Effects, from their stock 4.4.2 build?
Im pretty sure this is down to the software API that activates the opamp. (as it is very distinct), it even happens when you activate audio by using the rocker to increase the ringtone volume!?!?!???
It sounds like listening to a really cheap mp3 player with a low S/N ratio...
** edit I mean 'Play Music' not 'google play'
Hi,
I actually just registered to say this was very much present on my moto g on android 4.3 and is still the same on KitKat. It definitely sounds like a cheap mp3 player. Does anyone know of a fix?

Now this is getting weird. I think I'll install the ota to see how mine behaves. The G's audio quality decent enough imo. Probably above Android smartphone average. But what I like the most is that it's 100% silent, regardless of the volume setting, headphones or the amp.
Having said that, I will still get a USB DAC solution for it, which luckily has native support on both stock ROMs.

I don't know what you mean with "hiss", but since I updated mine (today - uk), i have started to notice some "clicks" in musics, that i didn't have before.
I was using PlayerPro, turned off the equalizer, uninstalled and reinstalled it again, and it was solved.
Google music, had no issues.

by hiss, I mean hiss. It is probably around 18KHz, and is similar tot he sound of RF interference on a stereo (alsmost like the snow screen sound on a tv).
It is not volume dependent so it is defenitely downstream from the DAC, and must be the opamp or downsteram from the opamp in the phone. It is most likely from a poor ground some where in the audio path (assuming the opamp isn't awful, anyone know the chip?). It could be due to the single board set up of the Moto G mainboard design. I'm guessing here, but if the PCB has the audio channel close to any of the ground of power channels, this would explain my hiss. If it is built to tight tollerance, this could also explain why some people have it, others don't.
In laymans terms, I'm saying the audio signal is 'dirty. If anyone has every used a PC with crappy audio on the motherboard, they will know exactly what this problem is like. When no program is using the audio driver, the board puts the audio to 'sleep', when you open a program that uses that audio driver, the audio wakes up and you get some hiss, noise through the audio and pc speakers. This is exactly what I experience with my moto G.
if im honest, it's unlistenable, however I'm a bit of an audiophile so I can appreciate for most people they won't see it as a problem..

I found 4.3 to already be noisy with the hiss when using my earphones, which have a low attenuation and so even low volumes sound loud on them. To get around this problem I bought an attenuator which connects between the phone and the earphones. Then I set the phone audio to maximum, and reduced the volume using the attenuator. Setting the phone audio to loud means the hiss volume is low compared to the volume of the sound coming out of the phone.
This is the attenuator I use:

I don't know what you mean with "hiss", but since I updated mine (today - uk), i have started to notice some "clicks" in musics, that i didn't have before.
I was using PlayerPro, turned off the equalizer, uninstalled and reinstalled it again, and it was solved.
Google music, had no issues.

this is a possibility, but its not ideal... sadly this is looking like a hardware issue not a software one though as if it was software, I'd expect it to be upstream of the opamp. The fact your attenuator solution works, is more evidence this is a downstream issue . (as implification induced noise increases with the square of the volume (assuming a logarithmic volume scale))
I'm on 4.4. I notice a slight hiss when music is coming out of the phones speaker, though its completely undetectable if the phone is at around half volume. No hiss when coming through headphones.

Please can you test something, with some sensitive in ear headphones (or in a quiet room if they are normal headphones.)
>Connect headphones to phone
>Make sure ALL apps are closed.
>turn the phones ring volume to zero
>you should hear silence.(regardless of what headphone volume is)
>On the home screen, Press the Up volume rocker 3 times quite quickly.
>On my phone, the headphones go from silent to Hiss, then I hear the 'Beep'.....'Beep' of the volume increase on top of the hiss. Wait 2 seconds after the second beep and you hear the Hiss abruptly stop, and you are back to silent.
I have this problem with all audio activity on the phone, but the ringtone volume trick is the easiest way to demonstrate it.

Or even easier, just press the volume down or up button once in any direction with headphones plugged in. Regardless of what it was set to and becomes set to, you will hear a faint background hum/hiss be emitted through the headphones for a second. This is fairly normal on any phone and even most audio devices. I don't know what you expect really in a smart phone that costs £129 in the UK. It is a compact environment to build so much electronics into and will never be a hifi device.
I tested with 3 phones on my desk right now and they all have a hiss when you first do something to make audio come through the headphones like quickly play and then pause a track. In fact, one phone (Samsung Galaxy Ace Plus) has not only a hiss, but a screech/high pitched whine as well. All of these "noises" that are detectable, become undetectable when volume of anything is turned up past the first or second bar anyway.

This is a fair point, and I agree is not surprising given the phones price. I think the reason I have posed this question was to a) determine if it could be software related (4.3 vs 4.4.2) but It doesn't looks so. b) Is it universal, or could be a slight lottery and maybe my phone is worse than others. As some people say they definitely have no issue. (granted it could be subjective)
Also, I would say, although it is present in most devices to some degree, it is noticeably worse on this phone than any other I have had. Multiple sony erricsons, galaxy Ace, Nokias.. And my last phone Galaxy S2 had extremely clean audio production. (i compared directly with moto g).
I do concede I am an audio snob though, so don't like listening to poor quality. I never really expected to use the moto g for music, but would have been a nice to have.

Yeah, it seems to me too that you are a bit more on the audio than most people
By the way, I was wondering up to which levels can you really say that you hear the hiss? As I've said before, for me it's definite hiss when muted and 1st level, weird feeling on the 2nd and I can't hear it from the 3rd.

Depends on the music. pop music which has a lot of mids and highs, the hiss isnt noticible from notch 4 up maybe.
Quiet music, classical, R&B & hihop with a lot of bass beats but not many highs, you can hear the background his up to maybe 2 notches off max. But its acceptable from maybe half volume.
tbh it's more of a shame than an issue. I didn't expect this to replace a decent mp3 player, would just have been convenient is all.
Hi all,
So I recently bought a new LG G3 - after having screen problems with the Oppo Find 7 - had the Oppo fully refunded, so was on the hunt for a new phone.
Bought the LG G3 instead - great phone (apart from the stupid button placement)...but there's a fundamental flaw with it - just sharing this here, to hear if anyone else has been testing it the way I have done in the video:
(Essentially the audio has a buzzing noise to it, when using the phone - this happens when you amplify the source)
I don't find it acceptable for a 2014 flagship phone to be like this.
I'm on the fence now to root it and/or flash another ROM OR just return it for a full refund - anyone else have any experience with different ROMs (ie 5.0 ROMs)?
EDIT:
I'm returning the phone: http://forum.xda-developers.com/showpost.php?p=57514537&postcount=12
Some test results: http://forum.xda-developers.com/showpost.php?p=57514889&postcount=13

That "beep beep" sound when connecting your audio jack appears to be unique to your device as I haven't seen any other G3 do that before.
Also, I stated in another thread about this issue, It only happens while the cpu is under load AND there is no audio.
Once the cpu load drops to idle the issue is gone.
Once there is audio playing the issue is gone too.
It's annoying while no audio is playing, But it's not gonna degrade your audio experience in any way what so ever when there is sound coming out of your phone.

Thanks for the input.
Well that's odd, I've gotten others saying the beep beep is normal, but the buzzing isn't lol.
Out of interest, do you have the same issue?
And it's also a matter of principle, rather than it also being a fundamental flaw in the design. No flagship phone should have such an issue.
Whilst music is playing it's not noticeable at the levels I play it at, but at low volumes, and whilst using the phone at the same time, I can hear the problem. I'll retest tomorrow to make sure.
Not because I'm looking it for it, but because something doesn't sound 'right'in my music.
If it's CPU causing it, then is it linked somewhat to the kernel (ramp up and down of the CPU) or is it due to the placement or 'communication' it has to do within the phone (hardware problem)?
Mine does the Beep beep thing when i plug in my phone to the sound system at my work. It's done it on every ROM i have tried. The hissing, i haven't heard for a while though.
To be honest though, it is completely unacceptable it's not been sorted though yet.

Hi !
I think the audio system is the only problem with this phone.
When hearphones are plugged and there's no sound, you can hear a weird sound (especially when you touch the screen).
I also have a problem when I listen to music, sometimes the music has a little lag, a little buzzing for less than a second, as if the phone didn't have the time to load the music. It sounds like an old used CD. It happens once every ten minutes approximately. I don't know if it comes from the fact that I listen to music from my SD card, which isn't a very good card (64Gb, 20$ on amazon). I should test it from internal storage to check that...
Anyway, I'm using ChupaChups ROM and the problem you're talking about is also present. But Chupa Chups is a stock-like ROM, so this isn't a surprise.
I'm planning on installing CyanogenMod to see the difference.
I'll report back here after that

Thank you!!
As for your issue - you tried disabling throttling from the secret menu?
I've done so - in order to avoid temp capping

What hidden menu ? Dev options ?
ChupaChups ROM includes a mod which allows the processor to have an higher temperature (I think the original limit is 65°, the mod is set to 75°). The mod is supposed to erase this kind of issue.

Well it's not much of a "mod" - just a setting that you enable/disable:

That's a link to what I did.
Essentially the reason I'm saying it for you - is the laggy nature of what you said - with my brief use of the G3, I noticed a little alg, until I disabled the temp and throttling

Okay, thanks for the info.
I just installed CyanogenMod 12 (The ROM looks very stable, but I only got it 20 minutes ago so...). The first thing I tested was the issue we're talking about here... It's also present on Cyanogen ! The problem does not come from the Stock ROM !

Legend - seems hardware related (as initially thought)
Unless CM use the same stock kernel - highly doubt that though!
OK guys - went into O2 store in the UK - they had a G3 on display.
(It was plugged in) - I could hear a LOT of static noise on my earphones with the amp connected.
Then I unplugged it from the mains - the static went away.
I then did the same tests as before and boom - same issue.
It's 100% not my device only and is present in the international G3 version.
My LG G3 is being returned tomorrow. It's unacceptable.

OK so I did tests -
Without the micro USB cord connected:
Audio playing - 0% volume (thus you can't hear anything) - static noise, no HDD-esk noise
Audio playing - 1st notch (you can hear music faintly) - static noise, no HDD-esk noise
Audio not playing - HDD-esk noise
WITH the micro USB cord connected - charging:
Audio not playing - Louder static noise, minimal HDD-esk noise
Audio playing - 0% volume (thus you can't hear anything) - louder static noise, no HDD-esk noise
Audio playing - 1st notch (you can hear music faintly) - louder static noise, no HDD-esk noise
Hope this helps everyone looking at this thread
So, I have a set of Sennheiser HD 598, a pair of Monster DNA headphones and Sennheiser CX275S in-ear earphones (for Android smartphones).
When I connect the HD 598 and the Monster DNA to the phone directly. I get no noise.
But when I connect the CX275S, I get the noise.
Could it be something to do with the impedance/resistance of the headphones and/or cable that is being used?
However I am not using an amp. Do you get the noise without the amp? Have you tried a variety of headsets??

Yes it can be the impedance - however this doesn't apply when I connect the amp -as it is picking up more than the source usually shows.
In other words - you CX earphones could be more sensitive (which I find surprising vs the HD 598) - but if you were to put an amp - I think all of them would show.
I've tested with a bunch of earphones and my headphones - all of which showed the same problem with the amp.
I know for sure now it's to do with the phone - now if some people would notice it or not with their given setup is another thing.
ie. their setup might not reveal the flaw (ie if I had never put the amp - I wouldn't have heard the problem).
Also - I've noticed a audible "click" / "lag" when music was changing. making me say: "Yup 100% this phone is being sent back"
Can't believe I'm back to my SGS3. over 3yrs old - no problems and trumps these flagship phones in terms of audio quality.
Just to add my part, the "beep beep" is normal when connecting headphones. I usually get a very quiet buzzing noise when I have the phone connected to a power source and have headphones in. I'll report back in a week, getting a warranty replacement so may be different

excellent thanks for letting me know - why are you getting a replacement? (this issue?)
I've already packaged mine ready for an amazon return.
I decided to pull out all the earphones and speakers that I have. And here are the results.
1. LG earphones that came with the phone - no noise
2. Old Samsung Galaxy S2 earphones - no noise
3. Old iRiver earphones - no noise
4. Sennheiser HD 239 headphones - no noise
5. Bose Soundlink speakers in aux mode using a cable - at the highest 2 levels of volume I can hear the noise.
So it may be an amplification issue.
I am not sure that LG would accept the product back here in Australia if I tried to return it as there is no noise with the supplied earphones and any problems with amps would probably be out of their warranty terms.

Not an amp issue - I think I showed that by comparing multiple devices.
It's the fact the source doesn't like to be amplified - and when done so, shows these problems quite easily.
The source (LG G3 jack) doesn't seem to be isolated/shielded well - that's the issue. Therefore normally nothing happens, crank the source up a little and it fails miserably.
It's 100% down to LG here - I won't say it again, but I've returned the LG G3 now. I'm done with their crap implementation. How on earth they would have missed it is beyond me.
Reviewers also need to wake up when they do audio tests. Useless.
