Stereo audio output lost after Dr46onized update on Lenovo Thinkpad (usually running hardened)

Audio output went mono (right only) from stereo after kernel updating; it might be an imagined coincidence but the result was perceived to occur after a bunch of Haskell pkgs came into the usual Garuda Assistant System Update batch stream.

I use Analog Surround 4.0 Output + Analog Stereo Input to keep mic available.

In the past I have had success solving audio issues by turning Pulse Audio off and keeping Pipewire, but it has not helped in this case.

I tried to apply a solution from the forum from May using the jamesDSP audio settings but package manager is failing to download from both AUR and ChaoticAur returning fail message "Error: Failed to prepare transaction invalid or corrupted database."

Any suggestions are appreciated, thx!

Makes it easier to read. I did it for you for now.

To me it looks like your pipewire is not installed correctly as in pipewire-alsa is definitely missing here but that might not be the only thing wrong here. Try to reinstall pipewire following this post.

Also, I would recommend removing sndio having two sound servers might be one of the reasons why you suddenly have no sound. Infact try removing this first and then go for reinstalling pipewire.

sudo pacman -Rns sndio

Thanks for these tips! I disabled pulse audio in settings but it comes automatically in my kernel updates. Your suggestion to remove it and install pipewire properly is also most welcome. Thanks!

P.s. Thanks very much for the hints on the CLI commands!
