I got an annoying issue with my default audio device. If I use Wayland, everything works just fine. However, I can’t switch to hybrid graphics with Wayland, so I have to use X. Using X switches my my default audio device from my prefered one to the HDMI, which of course doesn’t provide any sound through my DAC. I have to manually go to advanced sound settings and switch it back.
That’s not a huge task, but it sometimes switches back to HDMI, usually when I’m gaming on my VM. Also my mouse stops working at the same time.
Any ideas what’s going on?
I do not know why x and Wayland change default sounddevice, but a workaround could be to blacklisting HDMI sound in a way. Usually Pulseaudio on top of alsa is what handles sound.
cat /proc/asound/modules ?
And add module for HDMI like so
Here’s what I get with the cat command:
It’s funny the default audio device doesn’t switch to HDMI, but Analog audio instead. Maybe because my monitor has an anolog out?
I’ll try to blacklist HDMI when I get back home.
I believe I’ve found a fix for this on another topic: Default audio device (built-in audio) keeps changing to HDMI after screen sleep
Marking this as the solution.
