How to make a USB dac selection persistent

[tankas]

Hi,
my USB dac goes to stand-by mode once the youtube video or movie is over, and system automatically switches to motherboard dac. When I start next video 10s or more later, had to manually select USB output. How to make selected device persistent.
Also how to disable HDMI audio output/devices as I’m not using that.
Lastly I tried PulseEffects for equalisation but could not select “Pulseeffects for apps” as output option, like in my previous distros.
Any pointers welcome and thank you.

P.S. might be useful - xfce4, 5.11.1-arch1-1
PPS Saw another threat bit down about Pulse effects not running as intended. Will read it.

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

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.

Yes, info from the link worked a treat.

Nice, didn’t knew. Will read more about it.
Thanks a mill.
