hi running 

Armbian 25.2.3 stable 6.1.99-vendor-rk35xx (Ubuntu noble)

 

having to change audio every time on reboot (not sticking after selecting),and maybe not showing as they should ,currently using HDMI 0 but shows as below:

 

These commands work for me:

 

pactl list short sinks #shows available audio outputs
sudo -H nano /etc/pulse/default.pa #opens the file for editing
set-default-sink alsa_output.platform-hdmi0-sound.stereo-fallback #set your default audio output
rm -r ~/.config/pulse #delete all files in this folder

reboot
