Linux app failed to open after changing audio output

Hi, I’ve been using this app for a while. Thank you very much for your works.

I have this problem after changing the audio output from HDMI to aux or vice-versa (in OS audio setting). Then I need to change the audio source in app (from Monitor of Built-in Audio Digital Stereo (HDMI 2) to Monitor of Built-in Audio Analog Stereo) by restarting the app because the refresh function isn’t working. The app won’t open again. But after changing the audio output back and forth after 3-5 try it can be opened again. I use pop os 20.04.

For an example this app.log when it fails to open one time at 20:14:37:

Hi, the refresh button works in this version AudioRelay 0.22.
Hopefully the crash won’t happen again. :crossed_fingers:
