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).
Machine: ASUS G75V laptop.

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