Comment 18 for bug 1319457

Kernel from #4 fixes this for me but only the urb callback issue. When I connect my usb headset, I will randomly get either the loudspeaker or microphone but not both.

pactl list shows either profile
                output:analog-stereo: Analog Stereo Output (sinks: 1, sources: 0, priority. 6000)
                off: Off (sinks: 0, sources: 0, priority. 0)
or
                input:analog-mono: Analog Mono Input (sinks: 0, sources: 1, priority. 1)
                off: Off (sinks: 0, sources: 0, priority. 0)

but not both, which would be correct (or as with kernel 3.5.7.1):

                input:analog-mono: Analog Mono Input (sinks: 0, sources: 1, priority. 1)
                output:analog-stereo: Analog Stereo Output (sinks: 1, sources: 0, priority. 6000)
                output:analog-stereo+input:analog-mono: Analog Stereo Output + Analog Mono Input (sinks: 1, sources: 1, priority. 6001)
                off: Off (sinks: 0, sources: 0, priority. 0)
