Verified with 3.16.0-30, the audio mute LED still not working.

Another major blocker on this system is the fglrx driver issue, since the newer driver will be backported to Trusty, it will be great to have this fixed in Trusty too, thus we will be able to certify it with 3.13 LTS kernel.

Please install latest alsa daily dkms, then redo the test to see if it can fix this problem. If it can fix the problem, I am going to backport the fix to ubunutu utopic kernel. It is difficult to backport the fix to linux-3.13 since the fix relies on the pin quirk framework.

The fix for this problem should be:

The alsa daily build (oem-audio-hda-daily-dkms-0.201502051931~ubuntu14.04.1) fix the problem, the audio mute LED works now.
