Comment 2 for bug 1331915

Hi Kent,

It looks like we're missing a quirk entry for this machine, it's likely
one of those machines where you have to ask the user what (s)he plugged in.
You can read all about that here:

So, can you edit /etc/modprobe.d/alsa-base.conf and add the line
“options snd-hda-intel model=dell-headset-multi”, reboot and test and
see if it works?
