I'm testing whether realtime works when I open my obs since I can hear my mic there, but when I clicked Start audio conversion, it crashes I got an error on my terminal:

Traceback (most recent call last):
  File "/.../RVC/realtime_gui.py", line 1021, in <module>

    raise PortAudioError(errormsg, err)
sounddevice.PortAudioError: Error opening Stream: Device unavailable [PaErrorCode -9985]

This happens when I set my input to "USB 2.0..." because that's what my mic is connected to. It also happens when I set my output to headphones.
