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
I had the same issue when I updated to Ubuntu 19.10.
- Open PulseAudio Volume Control. I believe it's already installed by default.
- Click the Configuration tab.
- Find your HDMI device and set the Profile to Off.
If it's not install, you can install the PulseAudio control panel using:
sudo apt install pavucontrol

This solution is exactly what i needed and still works in 19.10 as of writing. (it isn't installed by default in 19.10) – Dylan Westra Jan 14 at 15:32
- Click on the speaker icon, top right. Choose 'Sound Settings...'
- Click on the Hardware tab
- Select the HDMI device and choose 'Off' from the pull-down menu.

10The Hardware tab seems to have disappeared in newer versions of Ubuntu (I'm using 13.10 and don't see it.) – Drew Noakes Nov 8 '13 at 19:28

Referring to GUI to solve these issues isn't a good idea, guis change. Radically and are contingent on config. – Owl Aug 4 '19 at 12:47
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.
I found that pavucontrol worked well for me
