I'd just like to see if anyone else is getting any audio issues, as I've noticed a few small things that marr the otherwise excellent audio quality that I get while listening to music:
- On bootup, the startup.wav sound often stutters, or is finely granulated.
- While navigating through menus, sometimes the audio stutters/is granulated. If I'm right, it correlates to the cpu clock speed being ramped up due to coming out of "sleep" mode. This is just speculation of course.
- Whenever audio is played, there is a very quiet but audible (with a reasonable set of headphones) click, followed by a quieter "hiss" which then plays throughout the audio being played, and for a short while after.
Now this last "symptom" I've heard on many audio devices, some much worse than others, with a rare few having no noticeable noise whatsoever. The Dell Streak I owned for a short time had a relatively loud and distinctive "click & hiss" combo - it was one of the reasons I changed to a Galaxy S. It just surprises me that a device where many people are praising it's audio playback qualities (for me) has some issues.
Anyways, I'd like to hear some thoughts on this, and maybe some people who have no issues whatsoever, with quality headphones, could show me that my particular device needs replacing - or that it is common to all devices.
I get the stuttering on start up everytime, I was also listening to some audio last night with headphones and there was lag and stuttering, I didnt hear any hiss but it was not a smooth process expecially switching between apps with music player running, it froze up for a few minutes.
I also tried going through the music player menus and not everytime but sometimes it would stutter just going into settings, at times this phone frustrates me more than my G1, but with the G1 i expected that, especially running eclair roms.
RUNNING JG5
I'm partly hoping that maybe FroYo, with it's cpu usage benefits, might help with the stuttering.
I'll also try to do a decent recording of what I mean later on tonight - Im at work with a laptop at the moment, so the recording quality is dire. I have no idea what I'm doing in terms of impedances/loads either - it means nothing to me
e: I've had a look in the other threads regarding audio - the one about the default EQ is interesting it must be said, but there are no direct implications for the issues I'm hearing here.
I should post my software version as well, though the problem has been endemic to the phone rather than the currently flashed rom - I currently use JM2, overlaid with SamSet pretties, Mimo's kernel and LauncherPro.
2 phones here with a hiss/whistle artifacts during the talk :-/
I recorded a vdieo the other day & the audio was totally trashed - all I got was gargling crackle. It was bad enough that I thought I'd got water in the speaker aperture! But playing music is fine (to my ears, anyway).
My speaker was working just fine the last few days and today, boom, got home and now it sounds like it's fuzzy and distorted. It won't play any songs at all almost, it's quiet and sounds like it's forcing to play. Anyone have the same?
tried restoring my first stock, fixed my wifi issue last time, but no sound fix still. what the hell happened...i opened the back and couldnt see anything. uninstalled volume+, but it wasn't giving issues earlier. Tried a new kernel but it was fine too, and that shouldn't affect sound? And if it did, the restore should have put it back? Not sure, might do a clean install of a custom rom and see what happens.
Your symptoms sound like what would happen if you blew the drivers. I'm not familiar with volume+ but I'm assuming it boosts the volume on your device past what the maximum volume in android? If that's the case it seems like it would be very easy overload the built in speakers on most devices as they are only designed to take a very small amount of power unlike dedicated speakers or headphones. Not sure why anyone would use an app like this(at least for the volume boosting function) as most devices have their volume limited for a reason. Even if the drivers themselves can handle more power, the amplification system in the device might not, which lead to clipping, something that in the long run can be just as damaging to a speaker as giving it too much juice. Exceeding the built in limits is just asking for trouble(Im not saying boosting a device's sound WILL blow the speakers, just that it very easily can).
That being said, if you were overloading the nexus speakers you should have heard a bit of distortion while listening to stuff and eventually they would have failed. If everything was working fine and then they suddenly stopped working, it's probably something else.

Bump
It worked fine at work, then went home and it got distorted. When I tried volume+, it never did anything anyway, so I never enabled it and eventually uninstalled it. Something happen in between, I did try a few kernels, but nothing in the threads said anything about ruining the speaker or sound. I flashed stock and nothing, still the same thing. Might have to RMA already :/
I've been having a weird audio issue with my Nexus 7 and was wondering if anyone else was having it. I search before starting this thread and couldn't find anything similar, which leads me to believe the answer is 'no', but thought I would ask anyway.
So my N7 was one of the first to be released. For a couple months I've had no major issues. A little screen lifting, but not enough to make me send it back. Some issues with the screen (what looks like burn in, but goes away) which has been heavily reported, but again, I can live with it. Both of those issues are well known and common, but this one just started up.
Every so often, when my N7 has been sitting idle and in standby mode for a while and I unlock it, I hear a "click" sound from the speaker. It normally makes that sound, but on occasion it sounds weird and clipped. When this happens, I lose audio. The only way to regain it is to either reboot the device, or manually lower the sound to zero, wait a few seconds, and then raise it up again. The latter method usually works, but once in a while I have to do it multiple times before the audio is restored. When the audio stops, it doesn't matter if it's the built in speakers or headphones - nothing.
This problem seems to only occur right after I wake it up. In other words, if I'm using it actively and I have sound, the sound works fine.
Again, this problem only started occurring about a month or so ago, and is only sporadic. At first, I thought it might have something to do with a new app I downloaded, but I eliminated that variable.
It's not a major problem, but it does get annoying every so often.
My N7 is stock firmware with a custom kernel (Motley) and rooted (obviously) with CWM recovery.
The logs don't indicate any issues. And since the audio comes back with me turning it off/on (usually), it seems more like a software issue.
Anyone else experiencing something similar?
Also, when the sound is working properly, it sounds great. No static or distortion or anything like that.
I have the same problem, at first i thought it was because of the kernels so i switch kernels from stock to motley then now i am on clemsyn. I do not know whether it is a software or hardware problem because my speakers sound perfectly alright, except the symptoms which you described.
My case is then sometimes when i unlock it, the normal click sound on unlock might be distorted and then for a period of time there will be no sound. The quick way to solve it is to plug in a headphone and then pull it back out, this will get the sound back immediately OR i can just wait for a while and the sound will be back. Again because of the speaker not having any other distortion during normal music playback, this might actually be a software problem, but it seems not many pple have documented this behaviour so hardware problem is also likely.

I think it could be a hardware defect with ours. Since you are the only other person to report the exact same symptoms, it seems to be rare. In my case, it occasionally happens even with the headphones in, so I don't think it's a speaker issue - more likely a sound card problem. If it was software, I think it would be much more commonly reported. Oh well.... Weird that it only started happening about a month or two after I owned it.
juz an update on my nexus 7 audio issue, i recently just flash franco kernel and the audio issue seemed to go away completely. i amnot sure whether its the overclocking or the undervolting that caused the problem but i am glad it is gone. Juz FYI.
I have a similar situation where the sound stops working randomly. It's rare, but maybe once a day. The volume buttons remain high but there is no sound. I have to reboot for the sound to come back. I am on Kaos Droid 3.8 Beta, with the Clemsyn Elite Battery Saving kernel.

I have a i9506 and it had perfect sound quality. After going from Lollipop DOF1 to DOF2 with arther97 kernel the sound trough headphones got really bad.(if 100% is perfect, it is at 10% quality). I have tried flashing older roms. I even tried to go KK again but it always has bad sound. When the phone is doing nothing its ok, but as soon as it has to make a sound there is a pop in the right channel and lots of noise, after about 5-6 secs of silence(headphones still make noise) it pops again and goes to normal. I tested the headphones and they are ok. It makes the same problem with other headphones and my PC stereo. There are other bugs like poping when chainging songs. I have tried v4d but it didnt fix it. It just made it bareble. (~70% quality, no poping between songs), but it still pops like hell and has lots of noise. The jack is clean, and its connected normaly to the motherboard. I have tried CM roms, kk roms, other kernels and no succes.
Hi!
A couple of months after I bought zuk z1, the sound just disappeared for notifications and when music was played through speaker, the speaker would make buzzing noise and it would fluctuate. Also, the sound level would fluctuate without even me touching the volume buttons. Sometimes, when I decreased the volume and increased it, it wouldn't increase and if I decrease it to zero, then even when I would increase it to full I wouldn't hear anything.
Flashing nuclearom fixed everything except the buzzing sound. To get rid of buzzing, I installed Viper4Android but instead of fixing it has brought back all the problems that existed earlier.
Also, the problem is only with phone speaker. The headphones and everything work fine.
Please help me!! I don't think it is a hardware issue because all these problems turn up on their own and they get fixed on their own for a time being.

Seems like you have nearly the same problem with the speaker:http://forum.xda-developers.com/zuk-z1/general/low-speaker-sound-t3500648
I think the sound problem could be an hardware issue

I said it's not a hardware fault because sometimes when I would clear data and cache of Audio FX and force stop it, everything would come back to normal. However it worked most of the times but not always.

And without audio fx? Did you wipe system, data every time you install other roms?
When I would force stop audio fx the sound would become normal. Yes. I follow the normal procedure before flashing roms which includes wiping everything.
I forgot to mention one more thing. The ringtones would work when there was no notification sound. And after I unlocked the bootloader, the notification sound problem was gone but the buzzing remained. I know it sounds freaky.
And if it's hardware or speaker problem the buzzing shouldn't be there at low volume. But in my phone, it's always there. In my experience, I feel like it's a software bug. When i listen to some song and it buzzes, I can notice that the volume increases and decreases on it's own as if the system is trying to create a balance.
