Public bug reported:

I have Jabra 2400 Biz headphone(with mic). Its not working in ubuntu
12.04. I killed pulse audio and restarted it .Following is the output :

"W: [pulseaudio] sink.c: Default and alternate sample rates are the same.
E: [alsa-sink] alsa-sink.c: ALSA woke us up to write new data to the device, 
but there was actually nothing to write!
E: [alsa-sink] alsa-sink.c: Most likely this is a bug in the ALSA driver 
'snd_usb_audio'. Please report this issue to the ALSA developers.
E: [alsa-sink] alsa-sink.c: We were woken up with POLLOUT set -- however a 
subsequent snd_pcm_avail() returned 0 or another value < min_avail."

Other Commands Output :

aplay -l
