Haswell HDMI Audio: Pin remains in D3 state

[David Henningsson]

When trying to enable HDMI audio on Haswell machines we sometimes come across the following symptom:

 - No audio output
 - When looking at the /proc/asound/cardX/codecX file, it shows for the active pin node, that the right channel is muted and that the pin is in D3 (powersave) mode.
 - It might be that this problem only happens when the computer is connected to AC power, and not when it's running on battery power.

Workaround patch.

Example from the /proc/asound/cardX/codecX file:
