Built-in speakers in monitor not recognised and not working after updates

You should consider updating BIOS for this motherboard

Asus website is showing 13 BIOS updates released since the version shown on your system
https://www.asus.com/Motherboards-Components/Motherboards/All-series/TUF-B450M-PLUS-GAMING/HelpDesk_BIOS/

OK just trying to figure out how to update. The files that I downloaded from that page extracts as an exe and cap files. I installed fwupd but I can’t run it from the command line with fwupd and I don’t see a GUI program for it.

I can’t see TUF B450M-PLUS GAMING on that asrock site.

Nevermind, I see fwupd - ArchWiki now.

You posted system information on another discussion, that is showing both PulseAudio and Pipewire are active

You can choose either:

  • Disable the pipewire systemd socket and service to continue using PulseAudio
    systemctl --user mask --now pipewire.socket &&
    systemctl --user stop pipewire.service
    

(KDE requires pipewire base package so uninstalling it is not possible for this DE)

OR

  • Install manjaro-pipewire metapackage to get the additional dependency files for Pipewire to replace PulseAudio

Thanks, however, pipewire is not running now:

           Sound Server-3: PulseAudio v: 14.2 running: yes 
           Sound Server-4: PipeWire v: 0.3.24 running: no

However, I ran that command as you suggested.
