errrr indeed!
Unfortunately it's still not working, i went to setup in qjackctl and changed to output to hw:3, hw:intel,3, hw:intel.3 hw:intel:3 and nothing worked
i also connected capture_1 to both playback_1 & 3 and and capture_2 to both playback_2 & 4.
The sound via HDMI still doesn't work, and the sound is coming from the pc speakers/headphones

  • Select the command cat /proc/asound/cards with your mouse or touchpad
  • Open a terminal and paste the command by simultaneously clicking on the left and right mouse/touchpad keys
  • Press Enter and copy/paste the results just like you did with the cat /proc/asound/cards command

Thanks. But I was deluded I guess because cat /proc/asound/cards doesn't show any HDMI stuff, aplay -l does that. And aplay dosn't show any HDMI entries. I have to check on my own notebook which has a similar codec and which has HDMI too and compare the output of aplay with your output.

You must type those commands in when the HDMI device is both connected and turned on, of course.

The thing to note when using HDMI under JACK is you must use JACK in 'Duplex Mode' ie where you define separate in/output devices as it is unlikely your HDMI device has any inputs and JACK won't like it otherwise. Your input device would usually be your onboard audio, if you specify one.

I have no idea what this means, I just wanna make Jack output to my HDMI

How do you start JACK? CLI, qjack, cadence?

If you look under the Setup/configure window of both qjackctl and cadence you will note you can either set your JACK device as an 'interface' (this handles both input and output and won't work for HDMI) or you use 'Duplex' mode where you define the IO devices separately. If you don't see your HDMI device in the output device section when its plugged in and turned on then chances are your HDMI audio is not supported by ALSA/ the kernel yet.

Another way to view your ALSA devices is to run alsamixer in a terminal then hit F6 - any mention of a HDMI audio device there?

"aplay -l" does not show any HDMI device in the only audio card that alsa detects. So I suspect the HDMI port is not on the onboard audio card. Is it on the video card instead? If so, what video card do you have?

lspci | grep -i vga
