Weird pipewire virtual device issue
I’m having an annoying issue with pipewire. I have a Scarlett 8i6 audio interface. I have it set to Pro Audio so that I can access all the input and output channels, and I have virtual devices defined to allow applications to access groups of channels as discrete devices.
For some reason, all applications keep automatically switching to my secondary (mono) output. I can sometimes get them to switch to my primary stereo output, but it’s only ever a one-off and they will switch back when the current media is done playing. any thoughts?
