Yes, that is what the issue is. Most of the time audio playback stops,
the speakers will no longer work.
Sometimes one speaker will stop working (L or R only).
Running the TAS script or alternatively the below 'permanent' fix
resolves the problem.
Anyone with Legion Pro 7i Gen 8 or TAS2781 with audio broken after
kernel 6.7.9, you can install this which automatically calls the
tas2781 script on the events that would lead to no audio.

After continued use of 6.8.7 and later 6.8.8, I can confirm using the
`./tas2781-2dev-on.sh 2` in my case as root regularly whenever audio goes out
works fine.
What needs to happen at the kernel level / in a patch to resolve this?

I had been using 6.7.9 for the last week with no issues.
I upgrade to 6.8.7, and within 3 minutes audio broken.
I save your script and run it

Sound works again, however:

A few things since I last posted:
After having done the below command...
`amixer -c 1 cset numid=3,name='Speaker Force Firmware Load' 1`
Every subsequent reboot the audio never broke. I had multiple 2+ hour
sessions with no issue.
I never re-ran the above command.

I agree. I am using endeavour os, but I've also verified my scenario on
nobara (fedora based).
I found I can somewhat reliably get the audio to fail on 6.8.5 by leaving

Hi, just confirming that on:
Lenovo Legion Pro 7i (Gen 8 / 2023) the no sound issue has regressed again on
6.8.5.
Last working version without any issues is 6.7.9 - which is odd
considering the original post lists this as not a regression?
alsamixer shows ALC287 under system info.
6.8.2-6.8.4
