How to make a USB dac selection persistent

@tankas

my USB dac goes to stand-by mode

Keeping a portable DAC/AMP awake

I was thinking about USB power saving, e.g. if you use powertop or TLP. PulseAudio will also suspend on idle: https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Pops_when_starting_and_stopping_playback

I tried PulseEffects for equalisation but could not select “Pulseeffects for apps” as output option

PulseEffects 5.0 switched to PipeWire rather than PulseAudio, so you can’t use it without installing PipeWire. You can use pulseeffects-legacy is you want to keep using PulseAudio.
