Ubuntu – No sound coming through HDMI to TV

hdmikubuntusound

I just built a PC and the sound test for HDMI in Phonon works but no other app does. My audio device is :ATI Technologies Inc RS880 Audio Device [Radeon HD 4200]. I'm running Kubuntu 11.04. It works when i plug in speakers in audio out. I can give any other hardware info if needed.

Best Answer

Answering for Kubuntu 18.04 Plasma 5.12

1- Go to PulseAudio Volume Control
2- Configuration
3- Profile: Select "Digital Stereo (HDMI) Output"
4- (Optional) System Settings -> Multimedia -> Audio Volume -> Advanced: Check the box "Automatically switch all running streams when a new output becomes available" this way you will not have to repeat steps 1-3 every time you plug in the HDMI cable to your TV.
