HI
Working ok with garuda KDE Dr4g0n1z3d with my laptop and external hdmi monitor with built-in speakers.

Video is ok but cannot set audio to be on monitor. Installed pavucontrol, but still, hdmi sound out not available. Restarted with Arch usb (endeavour OS) and Hdmi sound worked,

any hint will be much appreciated.
