audio on video output (composite video)
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 hdmi line into a TV hdmi input does not seem to produce audio to the TV set. The mobo has separate audio ports for input and output. However, the spec on the MOBO (ASRock H310CM-HDV/M.2) under Audio reads: "7.1CH HD Audio (REaltek ALC887 Audio codec) To configure 7.1 CH HD Audio, it is required to use an HD front panel audio module and enable the multi-channel audio feature through the audio driver." The spec sheet has a bunch of such gobbledigook, some of which says to enable or disable things related to the audio. But not how to do so. At any rate, the HDMI port of the computer, on the MOBO, is very touchy. It would not tolerate an HDMI powered splitter box, that I put in to try and drive the TV set along with the local monitor. (Both on HDMI at the time.) (Everything interacts: I was driving the local monitor with the DVI connector, but it would not tolerate an HDMI cable at the same time.) As a result of the above, I installed an old GeForce GTX 550Ti and am now running the monitor and the remote TV thru the aforementioned powered HDMI splitter and that mostly works, except still no audio on the TV. It also takes a L O N G time for the monitor to come alive at boot, and once it did not--it came up in text screen. I would buy a modern video card, but I have no reason to believe it would work any better, if not at least faster. --doug

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 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)
