Switching VTs duplicates audio devices

Switching VTs duplicates audio devices like this:

I'm not sure where the bug is in.

Only the bottommost devices(bottom headphones/microphones) can be used and their volumes adjusted. The slider works but the keyboard keys to adjust them don't affect the volume or the slider, and the OSD shows but the volume is bound(eg. can only be 30% or 40%).

$ wpctl status
