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.

  1. Open PulseAudio Volume Control. I believe it's already installed by default.
  2. Click the Configuration tab.
  3. 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

  1. Click on the speaker icon, top right. Choose 'Sound Settings...'
  2. Click on the Hardware tab
  3. Select the HDMI device and choose 'Off' from the pull-down menu.

As per other answer:

Off mode in pavucontrol lives it's own life and is not persistent.

Using load-module module-switch-on-port-available in /etc/pulse/default.pa does not look like a desired solution.

Another approach:

  • Sudo Edit: /etc/modprobe.d/blacklist.conf

  • Add: blacklist snd_hda_codec_hdmi

  • Run: pulseaudio -k to restart pulseaudio.

Downside: even with it blacklisted it re-appear if it is on a device that is attached after boot. E.g: I have 6 monitors where one have HDMI-audio. If I de-activate the HDMI monitor and then activate it the HDMI-audio for it is activated. Have not investigate why.

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.
