Comment 63 for bug 178442

@paul: according to http://ubuntuforums.org/showthread.php?t=1268856 your card's subsystem device id is 0xd634, so you need to:

- Make sure you entirely remove any leftovers from previous attempts to fix the problem.

- Create a file /etc/udev/rules.d/ice1712-pulseaudio-workaround.rules with the following contents:

---
SUBSYSTEM!="sound", GOTO="ice1712_end"
ACTION!="change", GOTO="ice1712_end"
KERNEL!="card*", GOTO="ice1712_end"

SUBSYSTEMS=="pci", ATTRS{vendor}=="0x1412", ATTRS{device}=="0x1712", ATTRS{subsystem_vendor}=="0x1412", ATTRS{subsystem_device}=="0xd634", ENV{PULSE_PROFILE_SET}="via-ice1712.conf"

LABEL="ice1712_end"
---

- Create a file /usr/share/pulseaudio/alsa-mixer/profile-sets/via-ice1712.conf whose contents should be those of http://launchpadlibrarian.net/34620379/via-ice1712.conf, or those of the second "code" block in http://ubuntuforums.org/showpost.php?p=7965283&postcount=4.

- I think you should be able to run "pulseaudio --kill && pulseaudio --start" and have it working on the spot, but if not, try rebooting.
