Weird bug about audio offload

Many in China have encountered that some music apps have no response after playing for a while.

This is a strange problem, as there is nothing wrong shows in the logcat.

As far as I know, all the roms other than PA have the problem.

For me, I delete all the code about compress offload in audio_policy.xml, and it works.

Is there a more "polite" solution?

Answer 1 · 2016-08-23T08:49:17.000Z

I delete this.

compress_offload {
        sampling_rates 8000|11025|12000|16000|22050|24000|32000|44100|48000|64000|88200|96000|176400|192000

Another bug.

When I press power button to lock, if the phone is not entirely locked yet, press on physical button will wake up the phone again.

Answer 3 · 2016-08-23T10:28:53.000Z

On what build are you on?

When I press power button to lock, if the phone is not entirely locked yet, press on physical button will wake up the phone again.

This is not there for me on 0.3-beta (my build)

I delete this.

This is completely fine imo.

Answer 4 · 2016-08-23T10:31:49.000Z

@regalstreak

0.4.1beta, besides, this is here with me at least on 0.3.1 beta, I think.

Besides, is there anyway to disable compress offload in build.prop?

Answer 5 · 2016-08-23T16:17:00.000Z

For me, I delete all the code about compress offload in audio_policy.xml, and it works.

That works perfectly fine? No side effects? Then let's remove it.

Answer 6 · 2016-08-23T16:18:54.000Z

Fine, I have posted the method on Chinese One plus BBS , and they gave thumbs up

Answer 7 · 2016-08-23T16:34:03.000Z

Ok, fixed it, please check it here if it is OK like that.

Answer 8 · 2016-08-23T16:40:47.000Z

OK, but I will try other ways to fix it as this way is kind of brute, guess it is because of issue about audio buffer somehow.

Besides, noticed the another bug above?

Answer 9 · 2016-08-23T17:59:46.000Z

Another bug.

When I press power button to lock, if the phone is not entirely locked yet, press on physical button will wake up the phone again.

I don't get you, isn't that normal?

Answer 10 · 2016-08-24T02:41:10.000Z

I mean after press power key to lock the phone, there is an anime through the phone lock, and if I press home/back/recent button, the screen will wake up again.

I never have this on CM/AOSPA, and it makes me have to lock the phone twice.

Answer 11 · 2016-08-24T02:42:04.000Z

By the way, the 1344MHz issue must be in the kernel, I will try go through it.

@aviraxp
I found a difference in bitrate for audio_policy.conf
In xos it's set to 16bit, but in oos3.0.2 it's set to 24bit. Have you tried changing that?

OOS3.0.2 audio_policy.conf:

compress_offload {
        sampling_rates 8000|11025|12000|16000|22050|24000|32000|44100|48000|64000|88200|96000|176400|192000

Answer 13 · 2016-08-24T07:11:48.000Z

Actually, I tried to disable 16 and 24 bit PCM, and it doesn't work.

I wil try to enable deep buffer, since when bufffer was set to 1024 anr reduces a lot.

Answer 14 · 2016-08-24T07:16:17.000Z

And PCM is disabled in makefile.

Answer 15 · 2016-08-24T08:28:05.000Z

Yes, we picked RayManFX's commits for these, he removed all the broken audio shit

Answer 16 · 2016-08-24T16:31:54.000Z

Guys can someone give me a quick summary what's going on. Seems that nobody likes me, whenever I am not here, everyone is doing stuff lol

Answer 17 · 2016-08-24T16:32:48.000Z

I mean after press power key to lock the phone, there is an anime through the phone lock, and if I press home/back/recent button, the screen will wake up again.

I never have this on CM/AOSPA, and it makes me have to lock the phone twice.

Oh yeah you are right, checked again...
