audio devices
Status in “linux” package in Ubuntu:
Expired
Bug description:
The 3.8.0-24.35 kernel update in raring introduced sporadic failure of
USB audio devices. The symptoms are that the device suddenly stops
working and you get the following dmesg output:
[ 7532.838274] cannot submit urb (err = -18)
[ 7532.838283] cannot submit urb (err = -18)
[ 7532.838291] cannot submit urb (err = -18)
[ 7532.842224] delay: estimated 288, actual 96
[ 7532.922160] delay: estimated 432, actual 96

The fix hasn't been backported to 3.8 yet, but as this bug was
introduced to raring by pulling upstream kernel changes, it would be
nice to backport the fix to raring as soon as possible.
