Weird Audio Issue

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.

Audio popping across kernels?

Hi, I am having a problem with my audio and wanted to see if anyone knew of a solution. Since flashing the 3/02 version of KTManta, I started having faint crackling noises in the audio when on Youtube or Play Music. I then flashed Trinity TX4G and it stopped. Last night I flashed TX5G and it started happening again, but when I reflashed TX4G it remained, but not as bad. I was wondering if there is any solution to the issue, as it seems to be kernel-based. Thanks!

Any ideas? I haven't had a chance to test it further, but I plan on trying some things out over the weekend.

On other devices people had found that a sample time of under 20,000 could cause audio crackling and popping.
Also you can get audio problems if your CPU speed is not going high enough to run things properly, which would be caused by needing to lower your up_threshold, or use a new governor.

[Q] Various sound problems across various ROMs

Hi,
I'm experiencing many sound problems on my U8800Pro. Almost every ROM has it's own specific sound problems, for example MIUIv5 or CM10 have a lot of junk noise (which I cant identify, it just plays horrible) when playing from the back speaker. Some ROM's (i think shendu) are playing only one channel (mono) from the back speaker (which, for example, makes "Riders on the storm" or some Beattles unlistenable) but the quality is very good.
The only ROM I've come across, which makes a really good sound is ICEdroidV1 (because it's a modified stock rom)(and Stock, of course).
Is there a way how to "backport" "drivers" or some libs in order to resolve these issues across every ROM?
Call Sound and Mic sound are another story. On some ROM's, people can hear me good but I hear them really poor (some CM10)(which makes the phone unusable for example in bar or on the bus), on the ICEdroidV1 I can hear beatifully but in order to be heard, I have to have the phone really tightly to my face (I think that the second microphone is not working, but not sure).
I know these are really ROM specific issues, but do we have some universal fix for these issues?
It's really one of those issues which makes me hate this phone. (And, of course, the stock roms are slow and buggy). It makes me even think about buying a different phone but also, as a longtime linux user, hurts my head, because the hardware of the phone is pretty good and it fits all my needs --- it's the software that's putting me off.
If needed (but I think everyone knows what I'm talking about) I can record the sound and upload it here.
Thanks

Speaker Sound Quality on Nougat.

After Nougat update i am experiencing a really drop in quality from the speakers. They sound really noissy, saturated and they cripple a lot, specially at high volume. I notice it in music and in notifications sound. In marshmallow the sound was amazing and now i feel it sound like crap.
Does anyone have the same problem or are just my speakers. Even the voice in youtube videod has s noissy horrible sound..
Thanks!

I only noticed that sound volume is lovered, especially in youtube app.

Someone else had mentioned this in another thread (can't find it atm), but most people replied they didn't have that issue so it was thought this was a one-off problem, and to my knowledge no one else mentioned it again here or on other forums I frequent.
I would suggest starting with a full factory reset, and test with just the stock device prior to any unnecessary apps being loaded. This upgrade is pretty big, a factory upgrade is recommended if you have any issues at all.

Allready did a factory reset! Also Motorola block the acces to sound seetings so you can't change the speaker equalization, etc, it is imposible for an app to change the general system audio output, only in app sound can be changed.
Thanks anyway!

How to fix low mic volume in custom roms?

I would like to preface this by saying I love all the Custom ROM's available, especially the Android 10 ones. But, I've noticed one problem shared by all the ROM's I've tested so far (almost all). It's that the mic quality is simply horrible on every single one of them. The first thing I do when I download a Custom ROM is to test the mic using the Google Recorder app and so far, no custom ROM has even come close the loudness and quality of stock. I wouldn't mind if the mic quality was bad, but that's not the biggest problem. The biggest problem is that the mic VOLUME is extremely low. I have to shout while calling just so the other person can hear me. How do I fix this problem? The same problem cropped up a lot on Pie ROM's too. I've tried editing the mixer_paths.xml but I don't really know where to look.
I would greatly appreciate if anyone could help me. Cheers.

Use kernel with mic gain and increase it to your liking.
