Comment 25 for bug 1793640

I removed timidity (without even purging) and my sound satarted working normally, even though my audio group still contains two users: pulse and timidity. This group is supposed to be empty?

I reinstalled timidity and timidity-daemon and the problem returned. I removed timidity from the audio group and rebooted and the problem was again fixed. The timidity program works. (I don't know what the daemon does.)
