Hi, this audio device has been causing some trouble for quit a couple of people. There has been a lot of work on this device in recent alsa versions. Are you using a realtime kernel? You could try to set options snd-hda-intel model=ref position_fix=1 enable=1 index=0 in /etc/modprobe.d/sound (might be another file, this depends on your distro), the important being position_fix which can be 0 to 3. Try sudo modinfo snd-hda-intel to get information on this, and different values for position_fix. You'll need to reboot to see changes. For some this worked....
