powertop reports that Intel CougarPoint HDMI is 100% active and there are reports that this device consumes a lot of power. If that is so, I would like to disable it as I never use it. Is there a way I can disable it?
I am using Ubuntu 11.10

If it's not install, you can install the PulseAudio control panel using:
sudo apt install pavucontrol
To disable the audio device (not just mute) run in terminal
sudo alsa force-unload
alsa
options are
unload|reload|force-unload|force-reload|suspend|resume
In case you require the audio device at a later stage.
