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.
If it's not install, you can install the PulseAudio control panel using:
sudo apt install pavucontrol
