Sound stop working after kernel update to 5.10.X

On my LENOVO Yoga Slim 7 14ARE05 (AMD ryzen) sound not working properly after update to kernel 5.10.X. It works fine on kernel 5.9.X, but now after update, internal mic is not even found and speakers has only left channel working.

In alsa info output I found that snd_acp3x_rn module is not loaded and on 5.9.X it was. Any suggestions on how to fix that sound issues?

Hi, new community member here, just looking for some help with an issue.

I’ve also been having sound problems after the kernel update to 5.10.X. Everything appears normal (devices appear in logs, /dev, and mixer apps; kernel modules loaded; no errors reported) but no sound comes out of either the (internal) speakers or headphones. Only once has sound worked as normal (after a reboot) for me on a 5.10.X kernel. That was on kernel 5.10.10. After a later reboot into that same kernel, though, sound stopped working again. I have not tested every 5.10.X kernel; only the more recent ones that were automatically installed by Software Updates (I use the KDE spin).

There are two entries when I search for ‘Audio’ in the output of “sudo lspci -v | less”:

Am not very knowledgeable about the Linux sound infrastructure but will provide any further details as requested.

Anybody?

I found a workaround at least, so I no longer have to boot into an older kernel to have functional sound:
