Ok, let's look again at this bug. First, unfortunately bug 1169984 made it into the 13.04 release, which hits many machines with HDMI audio. So any problems in 13.04 is likely to be bug 1169984.
Second, there is a patch "ALSA: hda - hdmi: Make jacks phantom, if they're not detectable" that hopefully fixes most of these errors. What I recommend at this point (to get the above fix without getting bug 1169984 ) is to install the latest HDA driver and reboot ( https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS ). If this helps, you're likely being helped by the next proposed kernel in 13.04 too. If this does not help, you can do the following: * Install the hda-jack-retask package from https://launchpad.net/~diwic/+archive/hda * Start the program (run "hda-jack-retask" in a terminal). * Select the HDMI codec in the topmost combobox. (If you have more than one, and don't know which one is right, you might have to repeat the below steps for all codecs.) * Select "Advanced override" * On the HDMI pin that does not show up, click "override", then change "Jack detection" from "Present" to "Not present". * You can then either click "Apply now" and test this right away, or click "Install boot override" and reboot to test. Regardless of this is working or not, report back here and attach alsa- info ( https://wiki.ubuntu.com/Audio/AlsaInfo ).
