Bug Description
Binary package hint: linux-image-
After upgrading to Feisty, my USB audio device no longer works after hibernation and resume. The volume control applet shows it as being "muted", but it is not possible to un-mute it.
The device in question is a set of Harman-Kardon SoundSticks:
Bus 001 Device 006: ID 05fc:7849 Harman Multimedia
If I unplug the device and plug it back in, it still fails to work. Removing the sound modules from the kernel and reloading them results in an oops.
Please let me know if I can provide any other information regarding this problem.

Oh. Also, this is on AMD64. The USB controller is:
