Ubuntu – How to disable an audio HDMI device

hdmisound

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

Best Answer

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
