Weird Audio Issue - Nexus 7 Q&A, Help & Troubleshooting

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.

Possible software speaker problem where they occasionally cut out?

So I'm having an issue with the speakers on my Nexus 7, and it's almost definitely not that same one everyone else is experiencing where volume above 50% gets distorted.
On occasion, after waking my N7, what will happen is that whenever it first plays a sound, whether it's music, video, a notification, or the keyboard typing sound, the speakers will just kind of make a quick scratching/crackling sound and completely give out. However, sound will eventually return completely to normal if I A. just continue to use the tablet for a minute or so, B. turn the display off and on, or C. turn the device off completely then reboot it. Outside of this weird issue, audio is completely fine. The tablet is currently unrooted, running the stock ROM.
Any thoughts? I'm really hesitant to RMA this one (I've RMA'd one before due to random creaking issues) because it's in perfect shape otherwise and don't really want to play the N7 lottery again if it's something that can be fixed either by myself or with a future update.
Anyone?
I have the same problem but no fix for you I also just wait it out a few seconds and it fixes itself...
I had problems where my n7's sound would completely cutout on netflix idk if its the app or speaker :/ ?

Nexus 7 speaker pop

Hi all,
Currently i'm having an issue. From time to time my speaker emits a loud sound like a pop and it stops working. No sound is emitted after that until i reboot or plug and unplug my headphones. Is this a HW issue or a software issue. Is this a known problem? I tried googling it but got no relevant results.

I own 2 , 1 I already had to replace due to a messed up screen upon delivery. Now both mine and my sons speakers male a crackle sound every now and then. Neither of my tabs have ever been turned up high at all and speaker quality still sounds fine but this really bugs the hell outa me. Anyone have any input on what this may be? (This faint crackle (feedback like) sounds only happens when I'm not using the tabs and nothing is playing)) They have never ran real hot that I'm aware of.. Not real into oc

It's been happening to mine recently, and occurs on a per app basis. If the popping sound happens in one app, no sound will come from that app until I close it from the recent apps menu.

My Nexus 7 gets the pop but only when the screen is off and no sound is playing. It also does not cause any issues or affect audio playback in any way. I've had other mobile devices that have done this and my best guess would be that my device i switching between a low and higher power state or vice versa (scanning for notification updates or entering a sleep state). I often notice it occurs shortly before I receive an email and it only happens when the screen has been off for at least 15-20 seconds.
Some of you clearly have a different problem but given the shared symptom, I'm wondering if it could be rooted in a similar cause.

anyone experience like this?
Do you have any apps installed that control the volume on their own?

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.

Frequent Audio Dropout

Anyone else getting repeated - and VERY frustrating - audio dropout? For me, it's happening incessantly with PocketCasts and Audible, but it would probably apply to other apps if I used them (I'm kind of a words-not-tunes guy!). There's a tiny little pop then the sound just stops. To get it back you have to pause and resume. Sometimes it takes a few attempts to get it going again. Sometimes, it requires a hard reboot of the phone altogether.
The WEIRD thing is that this isn't an audio focus issue. These apps continue to "play" all the while when they go silent. They don't pause. When they resume, I've missed stuff and have to rewind (more frustration!). Which makes me think it's to do with the overall audio system, rather than another app interfering with whatever I'm listening to.
So, this can happen anytime. But it does tend to happen more when I pocket my 6P. I thought maybe it's a proximity sensor thing, maybe the TGSP I'm using. But calls are fine, so I don't think it's that. Maybe it's an accelerometer thing? Maybe Fit is interfering? Who knows... ?
Anyone else experienced this, or got any solutions?

Are you using a Bluetooth headset or have it connected to a Bluetooth device when this happens?

No. No Bluetooth whatsoever, which is a bit alarming. And its not Fit because I uninstalled that - I already know I'm in perfect physical form - don't need my phone to tell me that Really can't figure it out and its becoming a bit RMA-y

Buzzing Sound

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.

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.
