I’d say that is more like a bug tracker than a database for if something works well

I had mic quality issues in discord for a while and it turned out it was discord’s echo/noise cancelation misbehaving. Turned it off and started using https://github.com/noisetorch/NoiseTorch instead. It’s actually way better at noise cancelation anyway.

Not that that’s necessarily what’s happening with your friend but thought I’d throw it out in case it is
