[82A1, Realtek ALC287, Speaker, Internal] Underruns, dropouts or crackling sound

[Gluttton]

Hello,

I'm using Ubuntu together with Windows on my laptop.

If I boot in Ubuntu after Windows sound doesn't work well (instead of system sounds I can hear only shot noise). To fix the issue I need to completely shut down the system (call Power Off via Ubuntu GUI) and then boot again in Ubuntu. Please note, that reboot (called via Ubuntu GUI) doesn't help to fix the issue.

Expected result: sound works well regardless of boot history.
Actual result: every time I boot in Ubuntu after Windows sound doesn't work.

Issue occurrence: 100%.

Environment:

when problems happens, please run:
$sudo sh -c 'echo 1 > /sys/module/snd_hda_codec/parameters/dump_coef'
Then run alsa-info to collect an alsa-info.txt (bad)

Then poweroff the machine and poweron it, make sure the audio works normally, run:
$sudo sh -c 'echo 1 > /sys/module/snd_hda_codec/parameters/dump_coef'
Then run alsa-info to collect an alsa-info.txt (good)

and upload the alsa-info.txt-bad and alsa-info.txt-good, let us compare them.

Please find the requested output attached.

When problem happens, please run each group of SET_COEF_INDEX and SET_PROC_COEF, then test if the audio changes normal or not:

[Hui Wang (hui.wang)]

So if only run below commands, does the audio become good or not?
sudo hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x08
sudo hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x4ab7

Or could you do a test to find the minimal group of commands to make the audio change normal?

[Gluttton (gluttton)]

> So if only run below commands, does the audio become good or not?

Yes, I confirm that the following lines are enough to make audio good:

sudo hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x08
sudo hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x4ab7

[Hui Wang (hui.wang)]

OK, thanks, let me ask for help from realtek side to explain the #9.

thx.

[Hui Wang (hui.wang)]

Please install this testing kernel and test it. thx.
