Mu USB headset stopped working after upgrading from raring to saucy on a Dell xps 13 laptop.
It appears as "digital stereo headset" in the sound settings in gnome control center, but choosing it does nothing now, and when I close and re-open the sound settings and the chosen sound is still "internal sound" (or something similar - my system language is not English).
In pavucontrol, my headset does not appear at all in the "Output Devices" tab - only internal sound and analogue headphones. Oddly it does appear in "Configuration" tab, where it is set to "combined analogue stereo".
In lsusb I see: Bus 003 Device 010: ID 03f0:8c07 Hewlett-Packard Digital Stereo Headset
Any idea about what I can do next?
