same issue as https://github.com/rbn42/panon/issues/78

@bpc1 Not the same as #78. That was due to an issue with python-soundcard, which was easily fixable.

I applied the fix locally and panon worked for a few weeks, but then it just broke randomly after one of the updates. I've verified that the patch I've made to soundcard is still there, so this is very likely a different issue.

I've had no success trying to debug the issue using journalctl.
