--- Comment #5 from Ivan <bsd at abinet.ru> ---
This is illogical. USB supports hot plug, so kernel must handle it without
stucking. I use audio with KVM b/w Linux. Windows and FreeBSD and I can't even
kill mixer as entire USB waits indefinitely.

My observations with FF playing youtube video
1. Windows - active playback resumes after FF restart
2. Linux - active playback resumes after FF restart
3. FreeBSD needs reset button.
