I also have the Legion Pro 7i Gen 8 16IRX8H, sound worked through all those kernel versions for me... But I do have another problem I wonder if it's related... Occasionally, my sound will just stop working. I can't get it working until I reboot... This tends to happen at a rate of less than once per day.

Last time it happened was yesterday. This time I decided to enable hibernate to see if resume from that would restore my sound (resuming from sleep doesn't work).

Anyway, the issue didn't happen to me for about a month... and then happened to me twice recently. Maybe it started around 6.8.4 or 6.8.5? When it happened yesterday, I was on 6.8.6.

The problem is so intermittent it's hard to pin it down to it starting with a specific kernel version...

But it makes me think maybe our problems are symptoms of the same issue.

How are you getting recent kernels? Are you self compiling? Are you using the Ubuntu mainline repo? Something else and/or some other distro entirely?

I'm compiling my own.

When this happens, audacious gives me some ALSA input/output error. I suspect some hook to tell the amps to wake up and play audio through the speakers hangs, but that's all I've got so far.

But sound issues related to TI's smart amps are definitely unrelated to this bug we're posting in. Someone should start a new bug for these issues if we hope to get more support.
