Looking further into this myself, it appears that the hdmi port of the mother board or a plug-in video card ought to have audio on it. This does not seem to be the case. Plugging the
i have had always problems on all my opensuse machines to get audio over hdmi or dvi (and at newer systems over displayport) to work. as far as i know its a configuration problem of the system. as a test i used windoofs, at same machine. it was producing audio over all 3 tested lines out of the box. (2 different computers) i never figured out what the problem was. i used always the analog audio out. - but i nearly never use it for watching movies
so first i suggest, if you own somewhere a windows boot stick try this, if it works, you are sure hardware is supporting it. (i do not see a reason why not)
I have one small machine working as media player and server. A mini box. It is connected via HDMI to the display, and it just works out of the box, using at this time openSUSE Leap 15.1 with XFCE. There is just one caveat: after boot it is mute. I have to connect once the earphones to the jack in the minibox and remove it, and the monitor plays sound instantly. If I open the audio mixer applet (I use Pulseaudio, of course), under "outputs devices" I see that it has active: Built-in Audio Digital Stereo (HDMI 3) HDMI / Display port 3 (plugged in) droplist wit no other option There is an advanced button: [X] PCM [ ] AC3 [ ] EAC3 [ ] DTS [ ] MPEG [ ] AAC I have no idea what the advanced options are, those are the defaults, never touched them. I have no idea why the HDMI is 3, because the machine has only one HDMI port. Under the configuration tab, I see built-in audio with a lot of options that I don't know what they do. But the default option works: Profile: Digital Stereo (HDMI 3) Ouput + Analog Stereo Input If I click, I see that the others have the word "(unplugged)" My desktop computer is using the DVI output because that's the cable my monitor came with a decade ago, connected to an older machine; thus the new machine got connected to the same port. No sound capability, it seems. The monitor says it also has VGA and HDMI and has speakers. My previous desktop computer, when connected to the second HDMI port of the media center display mentioned first, does not output sound via HDMI (another port of the display). I have not investigated. It plays via headphones when needed. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
