Audio popping across kernels? - Nexus 10 Q&A, Help & Troubleshooting

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.

Audio issues (stuttering and granulation, artefacts)

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).

Audio on video not working

Hi All,
When i take video with my omnia 7, it tapes without any sound. Has anyone come across this problem.
Thanks
I've come across this problem myself. I was at Soundwave back in February and half my videos had no sound, but some DID. I couldn't explain it. So I tried to experiment with it at home and found that the videos had audio each time. Thinking it was just some sort of weird one off thing, I went and used to phone to record a video at Future Music. Again, some of the videos had audio, some didn't.
I thought maybe the problem was that the audio at the concert was too loud and the noise cancellation mic was thinking EVERYTHING was noise, so it was cancelling everything, so I tried experimenting with the video for a couple of days after that. Again, some had audio, but some didn't this time, even when the volume levels of the ambient noise was very quiet.
So, after looking into it some more, I read one theory that it has something to do with a bug in how the Omnia 7 disables the speaker when something is plugged in (possibly into the head phone jack? I don't remember). I haven't really been able to find confirmation of this, but I'm hoping that after updating the phone, the problem has gone away.
I'll come back and post my experience when I know for sure
Thanks Deemar,
I have exact same problem, however I have only ever had one recording that actually recorded sound as well.
All the others have no sound
anyone????
same problem too :/ but i noticed the mic stopped working in other apps too such as shazam - it seems to do this from time to time randomly! very weird and annoying! havent noticed since nodo thought?
I haven't had the opportunity to experiment much since NoDo. But the videos I HAVE recorded since then (a grand total of two) have had audio. Knock wood, the problem might be solved...

[Q] Sound has.. desynced?

Only way to describe it. I have tried multiple sources (music, video, youtube, netflix, several games) and restarted the tablet twice. The sound from each speaker has very slightly de-synced itself or something. Im not sure how to describe it outside of everything now having a very clear echo. it seems the sound from the left speaker is just barely ahead of the right speaker. Also, sounds have become far more "tinny". This has only JUST started happening as of a few hours ago.
Ive had the tablet for about 2 months now and have never had this issue crop up before. Any suggestions?
minor addition since i found my headphones: this does NOT occur with headphones plugged in.
Edit: Little bit more testing shows that unplugging the headphones seems to correct the issue, but it re-appears after a restart. seams an easy fix, tried it several times during this 5 minute post interval. although i am hoping to find something that fixes it entirely.

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.

[Q] Noise when using headphones

When I bought the device 2,5 months ago I had no issues at all, but a few weeks ago I started noticing a lot of white noise when listening to music through the headphone jack on my Note 4, especially the right headphone. I have the feeling the issue started when I updated to NK4, but I'm not sure, so I don't want to downgrade just yet, since I have a lot of app data and it's quite a hassle to make a back up.
I was wondering if anyone else experiences this issue. I know it's present on some Nexus 5 and LG G3 devices as well. I have taken it to the Samsung store and they tried with their headphones as well and the issue persists. It gets even worse when I'm in the car using an aux cable to my car radio. Every time I accelerate or decelerate I hear a howling noise. Also when I'm just using the phone, not listening to any audio at all, all system sounds and notification sounds turned off, I often hear a clicking sound. At first I thought the back cover was a bit loose and made this sound, but it's actually coming from the speaker.
The issue is present in several apps: Youtube, TuneIn, MP3 Player and Google Play Music.
Is there anyone else who experiences such issues, because I'd rather not bring my phone in for repairs, as here in Holland that might take 2 to 6 weeks? And does anyone know if it is a software or a hardware issue, if anyone has found that downgrading might be a fix, I'd be happy to try that.
