Sound Quality

Anyone having issues with sound quality on their focus. Everytime a sound is played a pronounced hiss and distortion comes through my headphones. When listening to podcasts this hiss is very apparent. I wanted this phone to replace my ipod touch, which does not have this issue. Feedback please, thanks.

I do not have feedback or hiss in any music or app so far. My headset works well too. Not sure but something is up. Have you tried a hard reset and a new set of headphones?
I do notice low overall volume out of the stereo port though...compared to the Tilt 2 my car stereo needs to be turned up about 25% louder to be equivalent.

i think the sound is amazing, especially the external speakers.
As for headphones, have you put the headphones all the way in? It could be that or either worn-out wiring on the headphone cable.

My complaint about the sound is the alarm. When u test a sound for alarm is its very loud. When u set an alarm to go off it seems 1/2 as loud.

Ok, I have done a hard reset and tried with several headphones. The pronounced hiss is still there with some crackling when I change a song. My best guess is the audio output is not working properly. I did test the headphones on my ipod touch with no distortion coming through. Will be taking a trip to the att store for an exchange. While there I will test the floor model to confirm a problem with my device. I hope they are in stock because I took the last one two days ago. I love the phone and with clean audio output I will love it even more.

what became of the at&t store test?

I've had my Focus now for 10 days and I am completely satisfied with it. I have never had any sounds like you describe. Just clean, clear and much better reception than I had on my 2+ year old Fuze that I dearly loved. It was hard to switch to Samsung for me, but I think I made the right choice. So far I really like my Focus and the display is nothing short of fantastic!

I'm having a similiar hissing issue with my Focus as there seems to be a noticeable hiss at low volumes. The sound quality does not appear to be as good as my iPhone 3GS or Zune 80GB.
I'm still within my return window so I'm debating returning the phone and exchanging it for a new Focus.

is there any update on this? i'm really cutting it close to my 30 day warranty period, and i'm not sure if i should return the phone or not.
my issue is that when playing music in zune, you can hear a very faint hiss. if you pause the music, you can hear it for a half second before it stops outputting audio.

Try switching it for a new one while you're still in your window.

Make the switch... before the deadline. No harm no foul and really it is a legitimate complaint.

Headphones Distortion / Background Noise

Hi - just wondering if anyone else noticed some background noise / distortion when using headphones on the tab 7.7.
Happens when playing any sound and continues for 2-3 seconds after it stops. Tested with the stock buds and some replacement buds I picked up a few days ago. With my over the ear headphones I can't hear it though. Easiest way to test is just by playing a movie and pausing it.... there is a hissing noise for a few seconds afterwards.
Maybe related: even with headphones plugged in, notification sounds come out of the speakers - this is my first Android device so I'm not sure if that's normal or not.
Just wondering if anyone else is experiencing this or if it might be hardware related. Thanks!

Yeah I get that too. Doesn't really bother me though. I mean, it's not like I can still hear it while playing music or anything...

Mine's pretty noticable, even when playing music/videos. Weird that it's totally quiet with my over-the-ear headphones

Personally, I only really notice it if there's a trailing silence from music or videos, but while there's actually sound, I can't detect it.

audio hiss after 4.4.2 update.

<<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?
Thanks

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 see how this is on-topic, but of course, you can download the update either on Wi-Fi or mobile data.

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:

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.

Fundamental audio buzzing problem with a brand new LG G3...unacceptable!

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

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.

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

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.

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.

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.

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
EDIT: Using a pair of Audio Technica CKS-77X in ear headphones

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.

Cracks on the top IR Blaster (the one used for Quick Remote not for the camera) and your bottom microphone. Its a know defect with the G3 and they'll replace the phone for free

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.

Dongle Noise

Hello!
Just got my Essential Phone and I'm loving most of it so far. Unfortunately though, I'm having a problem with the DAC Dongle that came in the box. In combination with my Shure SE215 earbuds I get some terrible static noise whenever I start playing media from any app (doesn't matter if it's Video or only Audio). As soon as playback stops everything is totally quiet again with absolutely zero noise. Though it pops back in for a few seconds from time to time when I'm not listening to anything.
This is extremely annoying, especially when listening to really dynamic acoustic stuff on youtube or with movies, that tend to have quiet moments, as there are parts when the noise is louder than the stuff you're listening to.
Is there anyone with the same problem out here? Or could it be that I've gotten a bad adapter and getting the Pixel one might be a fix?
Thanks in advance!

I had 2 Essential phones and have not noticed static noise while playing anything. This you update the adapter? When you plug it in, there is a notification in the status bar telling you about the update. If you haven't updated, then try it, possible that the update fixes static noise. When I tried 2 of the phones, I update the adapter before listening to anything, so can't really confirm if update really fixes anything or you have a bad unit.
I do know that Google adapter works with Essential phone, although Essential adapter seems to be a bit louder.

I have the same problem. Asked for a new dongle, seems to be gone i'm hoping.

I can hear the noise for certain songs when the song is ending or at a "quiet" part of the song. Not for all songs. A bit weird.

Yeah, did the update the first time I plugged it in. I'll try it with a different pair of earbuds maybe, to see if that makes a different.
As for the replacement dongle mentioned in another post. Thats interesting. As I live in Germany though, that would probably be a bit complicated getting a hold of one directly, if you can somehow get them separately from essential.
Maybe I'll just order a Pixel dongle to see if that changes anything. Should at least work as I've read in a few other posts.

Hi Lauritz,
I'm experiencing exactly the same. Did you solve the issue finally? I realised that the only time I don't hear any static noise is when listening through HF Player from Onkyo. For any other app like Google Music, Spotify, Foobar I stil hear that terrible static noise.
Thanks for any info.
