I've created several VMs on my Unraid machine (based on a modest ASRock J5040-ITX) and they seem to work fine if I run them through VNC or Spice. But I've got my server next to a TV on my dining room and I'd like to be able to connect it to that TV through HDMI and then control it with a wireless keyboard and mouse.

I've tried Ubuntu and Fedora VMs and the run fine and show video without problems, but there's no sound even if the "dummy output" shows volume going up and down while playing a video in YouTube, for example. I've enabled the integrated sound card but nothing. I restart pulseaudio and confirm that the hardware is detected, but the hardware device detected is the S/PDIF one, not the analog output, and even trying to run alsamixer and changing levels there does nothing. The hardware and the support seems to be there, but I get no sound at all.

I've tried with Windows 10/11 but the problem there is even worse: there's no video output when I connect my unraid machine to the TV (I'm using the latest version -0.1.266-1- of the virtio drivers). Nothing. I've tried to check VM Manager in settings, but I can't get this to work and it would be great to have video and audio working through HDMI. Any ideas?

Normally you would use the audio built in to the HDMI output.

Yes, I thought so JonathanM, but I supposed that would work "out of the box". It doesn't, and I don't know how to fix this.

What options are available for the sound card dropdown?

Just "No" and that integrated chip from Intel.
