Comment 8 for bug 751681

Hi,

Upstream has asked for testing the new autoparser on this hardware. Could you please try the following:
1) Upgrade to latest alsa drivers: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules
2) Change /etc/modprobe.d/alsa-base.conf so the line now says "options snd-hda-intel model=auto" instead
3) Reboot, test that everything works the way it should, and report back here.

Thanks!
