The Linux audio stack is just baffling. After all these years it's still unreliable. I'm running Fedora 41 and often toggle between two audio devices, USB DAC and HDMI output. Sometimes when I change the output via Gnome settings my Flatpak apps don't care and keep playing with the previous output and other apps change as expected.

I've never edited any audio configs on this machine because I expected my 2 device setup and Gnome settings would be trivial enough for the latest Linux desktop audio solution.
