I tried to video record my son while he was speaking but at playback I could hardly hear his voice. He was about 1 meter apart and I could hear him as if he was 20m away. My voice sounded ok though. I assume that the microphone used for audio recording is the same as the phone mic with higher volume control.
Is everyone experiencing the same?
Also, Ihaven't found any controls to configure audio levels for different circumstances (i.e. phone ringer, speakerphone, speaker during conversation, etc.) Is it necessary to only configure volume when you are in that area (i.e only during conversation or during playback) and not all at once in a special control panel? (I hope you understand the last part as I don't know how to explain better)
I also feel that the playback volume for recorded video is too low (even on max volume). The audio quality is also not as good as I would hope. I have yet to test playback on a PC though.
Unfortunately anything related to Desire HD sound is low at the bottom line no matter recording or speaker it is.
agreed that recording volume is too low. But one thing i did find is that when you hold your phone to record, the natural position where your right hand holds the phone actually covers the microphone (well at least for me). So make sure your hand isnt covering that and it might improve sound a little.
But when i playback a recording on my laptop it sounds ok when i max the volume.. definitely audible.
Im also getting this low mic problem, made sure i was not covering mic, still low volume. Even took the case off, still no joy, cant believe they did not test this before launch
Please HTC sort this out
After playing back recorded videos on my laptop, i'd agree with SupremeBeaver that the volume is ok. The sound quality seems much better too, so i'm not too fussed now
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.

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.

I'm having the same issue and its driving me crazy! I read somewhere to try "Volume+" but apparently its not compatible with Jelly Bean...
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!!
It is noticed that while listening through headphones that the sound is being affected by some sort of 3D/spacial/EQ process that might give the impression of "punch" for movies but at the expense of phase-y sounding vocals and smeared high notes for music.
Yikes. Thst stuff is not good for music quality. No way to turn off? The settings options seems kind of scarce.
After playing around with various music players and headphones it seems that the audio is now OK.
Not sure what happened. It may have been a headphone jack issue. Audio sounds great now.
Oooops!
There is an issue with sound quality. Compared it to a Rockbox'ed Sandisk Clip Zip with a very wide stereo track 2-channel stereo track (fyi -- Brook Benton's "Kiddio" 1960). There is some EQ bast boost and high frequency crossfeed that narrows the stereo separation. I'm going to boot from CM and see if the problem persists.
For video I would not notice the issue, but could get to me listening to music with my Klipsch S4 buds.
Update:
It is not bad. Seems part of the issue is low gain which can be increased with Volume+ or other similar app function.
Volume+ did the trick for me. Jamming to some Coheed at the moment. Sounds as good as my other tablets now
The problem was never with volume -- I think stock has plenty of volume for driving Audio Technica ATH-900x. The problem is with some sort of audio processing that affects the soundstage and frequency response.
I am not hearing it using the Google player app. Gain is not the same as volume. Both need to correlate or weak quality.
SRS processing is used and applied at the headphone output. See HD+ file \system\etc\srs_processing.cfg
This is what I use, have my settings set to Jazz "my preference", audio sounds great, not talking about low resolution MP3's.

I understand the config issue, but I am not hearing it. I should hear the sound manipulation with cymbal decay as example, but not hearing it. Weird.
Playback in CM 10.1 has the correct stereo image.
so am I
so am I ,after checking
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.

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.

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.

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.

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.
