Hi,
I am observing an interaction between bttv and lsusb.
Running lsusb as an ordinary user will lead to drop of
sound from bttv for about a third of a second or so.
Doing that as root has no influence on sound. Sometimes
the failure is permanent and can be fixed by muting and unmuting.
I am puzzeled.
Regards
Oliver
