[SOLVED] Audio playback stops for unknown reason

Hi,

My friend gave me a tablet notebook a few days ago.
I removed Windows 10 and installed Arch Linux.
I found audio playback would stop for unknown reason.
Any ideas about how to solve this issue?
Thanks in advance.

I took a video about what happened, the audio playback stops at about 01:50.

Specifications:
MODEL: Genuine GenPad E10T3W
CPU: Intel ATOM Z3735F
Audio: ALC5642

Can you reproduce with local files/at all? There's a lot of stuff going on with a livestream that could lead to completely normal and expected dropouts, how sure are you there wasn't an issue with twitch/that stream in particular? Did you try playing back from a different source and that wasn't audible?

Thanks for reply.
Tried to play a video in local storage, but still the same.
Video/Auido playback stops after about 1~2 minutes.
It seems to be a bug in sof-firmware.
https://github.com/thesofproject/sof/issues/3868

I added the following modules parameters, but still no help.

options snd-intel-dspcfg dsp_driver=3
options snd_sof sof_debug=1

Re: [SOLVED] Audio playback stops for unknown reason

Today I found a workaround: Using old SST driver instead of new SOF driver solves the problem.

$ sudo sh -c "echo options snd_intel_dspcfg dsp_driver=2 > /etc/modprobe.d/snd_intel_dspcfg.conf"
