Something curious about the speaker volume lowering issue - Nexus 6 General

I've intermittently had an issue where the speaker volume lowers when listening to loud music or playing games. It's more noticeable on driving games where there is a constant drone of an engine keeping a baseline volume.
I've always thought it was a software issue but I've seen various other people had this problem and some even said an RMA cured it.
Well I did am RMA and i tested it on the new device and the issue had gone. Until now.
I thought I would have a quick blast on Need For Speed most wanted before bed. To my dismay, the issue had returned. It's the end of the day so I'm low on battery so I played whilst charging. I noticed the issue but also noticed i hadn't plugged my usb cable in properly. I plugged it in and by the end of the race, volume had returned. I raced again without issue. Then on the next race, i decided to pull the cable out and as the battery warning popped up, the volume dropped down instantly. I plugged the cable back in bit the volume didn't return for a short while. But it did return.
I've done a few more tests and it seems at low battery, i can consistently pull out the usb cable and the speaker volume will instantly drop. I've done some counting and it seems again consistently that volume gradually returns back to what it should be at what seems to be almost exactly 15 seconds.
I'm wondering now if this is some crazy battery saving measure like dropping the CPU to 2.2 GHz at 40%.
I'm hoping some of you guys with the same issue could do some testing and report back here to see if you witness the same kinds of trends. Maybe we could use this thread to catalogue our crazy hypotheses about what this may actually be too.
Test 1 with Battery 20% or lower, volume on full
-Plug in USB to charge
-Load a driving game (GT Racing 3 for example)
-Whilst driving with engine noise, pull cable out
Does the Volume lower? (Expected Yes)
When plugging the cable BACK in, does the volume return after about 15 seconds and remain high? (Expected Yes)
Test 2 (same as above) but at 40% battery
Does the Volume lower? (Expected Yes)
When plugging the cable BACK in, does the volume return after about 10 seconds and remain high? (Expected Yes)
Test 3 (same as above) but at 40% battery
Does the Volume lower? (Expected No)
Edit. Further results, its doing it at 30 and 40% battery too, though it seems to recover within 10 seconds now. I don't think its a feature because its not like the volume drops to a certain % then stays there, it fluctuates around at lower volumes..up and down.

Further to this, I've just tested the game at 60% and it didn't happen at all. I'm convinced it's a bug relating to how the CPU and GPU are throttled at "low" battery levels. I say low, it starts throttling at 40% which isn't low at all.
Please can anyone else with the speaker volume issue see if they can reproduce my findings?

Yep, same here, sound issues are common on the Nexus 6 as on Moto X. Motorola is already aware, you can look at their forums.

Same here as in you can reproduce the problems at specific battery %? Or same here you have an issue?
I do know people have this issue. It's just I noticed odd behaviour which may help pin it down. Can you test please if you haven't already?

Yes, at low battery it doesn't sound as loud as usual.
I'm also having static noise when calling and playing Mortal Kombat.
Motorola's sound drivers suck big time.

There is no solution? I'm really pissed off with this issue. I can't enjoy my music.

I test it with Poweramp max volume. Volume lowering when 20% below. But when I plug it to the charger the volume slowly comes back. Maybe it's a SW issue or feature. (Fck I hate this) That when the battery is below 20% they will optimize the speaker. Motorola should fix this issues. Such a shame to experience this on a Nexus phone.

Thanks for testing.
I think it is Software affecting hardware. I don't think it is intended though because when the volume lowers, it doesn't seem to stay at a single volume, it kind of fades up and down a bit.

It's a software issue. Motorola already stated that. One guy exchanged his phone 4 times with the same issue (static sound from battery when low on battery)

We're not talking about static though. But what software are they putting that issue down to?

I know

My device gets staticy and distorted when turned up above 50% volume, whether the battery is charged or not.
And whenever i get a call, the ringer is real low then blasts up to full volume all the sudden

I think it's more of a software issue, as with any custom rom or kernel, it seems to operate properly at least on my device, but now that i'm on M, i'm seeing this volume-dropping issue. How many people running custom roms/kernels have this issue?

Mine does it no matter what im running

Has anyone increased output sound volume on the phone yet? *#0002*28346# - Audio con

Love the phone but I think the audio volume output is totally junk.
Has anyone used *#0002*28346# - Audio control utility. or somethign similar to boost audio output on the audio jack?
Which audio output would this apply to? Or there just one? My Focus doesn't act like there's just one control.
Audio output level of the Zune player is definitely very low for me. Audio output level for the phone (ear) is just 'OK', but the speakerphone is very loud. Even if I turn it down to zero I can still hear the conversation. So strange.
... well I just went through that diagnosis screen and couldn't make heads or tails out of it. If anyone happens to figure that out, and determine if we can boost audio output from the headset jack that would be much appreciated!
I am specifically talking about the headset. I think the focus breaks it down like this: headset, speakerphone, earpiece.
Like you said, speakerphone is fine, if not too fine.
Earpiece is barely controllable while the headset (3.5 mm jack) is god awful.
There is currently a WP7 bug that causes game audio to impact audio on the phone. For example, if you are playing a game and you turn audio down to 15 (50%) and then exit the game, the highest volume level you can reach on the phone is 50%. Even if you then turn the volume up to 30 (100%), you are actually getting a level of 50%.
If you are encountering this problem, you'll notice that rebooting your phone will cause earbud/headphone volume to increase dramatically. An easier way to work around it is to go back into your game (any game with audio) and turn the volume back up all the way. If you then exit the game, audio levels should be good.
Microsoft is aware of this.

Interesting, thanks for the heads up!
I've tried *#0002*28346# but I don't know how to enhance the sound.
The sound is terrible in Focus.
Is there any way to install HTC Sound Enhancer? HTC HD7 it's much better volume in earphones.
I went to *#0002*28346#. Clicked read. Set system, class, and device gain to 10 (was 5 allthough some report it was 7). Volume was much higher via the headphone jack. I then read this thread regarding the game volume problem. I went into a game and put the volume all the way up. Went back to play audio via the zune hub. Volume was back to the low volume that it was originally at. I went back to *#0002*28346# and sure enough, The values reverted back to 5. So it appears the games are setting those values back to default every time you change the volume from within a game. I will have to test again, going into a game and not changing the volume to see if that too will reset it to default.
Do you guys mind complaining in this thread ..http://social.answers.microsoft.com...ad9-5e12-465d-a0fb-b9465179b436?prof=required
MS is still not taking any notice. It is kind of appalling to see such a nice phone as the Focus and Omnia suffer under such a silly bug.
Thanks Denis!!!!
It worked!
1 - PLUG YOUR EARPHONE
2 - ##634# TAPE CALL
3 - in diagnosis mode tape *#0002*28346#
4 - click GET on Device Gain
5 - in 'device gain' leave number 5, set 1500 (max) and -1100 (low)
6 - click set
7 - MAKE SURE AUDIENCE.CFG IS ON
reboot your phone (turn off, turn on)

[Q] Volume automatically increase

hi, mine is XXUBMJ1, after 3 weeks of usage, the volume automatically increase sometimes, what could be the problem, is it a bug or hardware ? should upgrade the firmware ?

Then I have no idea, sorry. My other guess would be is that you're accidentally pressing the volume key in you pocket or something without realizing it. You could try factory resetting the phone. It can sometimes fox weird issued like yours.

have u check the adaptive option under the settings->sound->adapt sound?
Could it be that the adaptive sound is processing at certain point of time trying to give you the best sound that its think of?
Yes, I have experienced this under the following conditions:
-Phone just purchased, unrooted, completely stock. Playing music with PowerAmp with and without the EQ/Tone/Limit features, also happened with stock music app. The effect nearly blew out my eardrums once, but it happened several times. Music would play and very suddenly there would be a violent increase in sound, almost as if an EQ crashed. Sound went back to normal after I pressed the volume rocker in either direction. I am not so sure that this has to do with Adaptive Sound because I remember experiencing the same problem before and after i configured it. Overall, incredibly annoying and dangerous for my ears.
-Phone rooted, Viper4Android installed as a user app. The same problem happens using PowerAmp, Xenoamp and stock music app, but the increase is not so violent (not sure why, yet). Marginally tolerable, but still very annoying.
I have not found a fix yet, but still keeping an eye open.
That being said, my phone has music playing almost all day every day so I probably encounter the problem more often than others. I use earbuds, headphones and my car stereo. There is a Droid-Life.com review that mentions the issue and credits it to the phone's audio jack: http://www.droid-life.com/2013/10/01/samsung-galaxy-note-3-review/
See the subsection for Audio Jack Issues. Here is an excerpt:
"Then, after a few minutes without touching anything while at full volume, the volume just explodes and you are left deafened by the surprise volume attack."
I would be interested to see if anyone reports the problem when playing music via the phone's speaker.

[Update] Looks like this is not an isolated issue. My friend's wife also facing the same problem and she sent in to reflash the unit at Samsung Care Center and the problem just disappear. My friend told me factory reset doesn't help though.
I have exactly the same issue you have. Same XXUBMJ1 ans using the device for a month now. Unknown and just reported to Samsung and was asked to walk in to get advice.

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 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.

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.

Volume too low until 70% and suddenly increases to audible level above that?

Hello Guys,
I have observed this since day 1 on my nexus 6p, that up till 70% volume level (volume steps), the sound is barely audible in lightly noisy room and then from 75% to 100% (volume steps) volume increases drastically and is loud, crisp & clear!
Are you having same kind of behavior on your device as well? If so, is it an issue or is it intended?

+1 for this, been trying to find service menu code to play around with the Volume levels and see if it fixes it.

No man, I am trying to solve couple of issues
1) Volume is not audible until you raise it to 3/4 or more.
2) Volume through headphones suck.
3) Trying to find a fully functional in ear headphones - Is a daunting task..Still researching.
Bumping up this thread for more people to share their observations and solution if they found any.
Mine has the same behaviour.
Having the same issue. Volume is essentially nonexistent until about 75-80% then it becomes loud as ****.
Usually only happens if I get a notification while watching a youtube video. Very annoying and its obviously software.

Volume Fluctuations

So basically I've had an audio problem for all things (Bluetooth, earphones and speaker), where I've got media playing at, say 50% on the slider bar, then it suddenly drops to like 10% without the bar position changing before it suddenly returns to the normal state. This is extremely random for me and irritating, as the volume can stay low for an extended period of time, especially since by the time the volume returns to normal, I've raised the volume so it makes me jump when it suddenly blares a YouTube volume. Has anyone found a solution?
I have a rooted Samsung note 4 with the lamlazy note 7 port rom
Many thanks in advance
