Add local audio support for HDMI output.

[tornadox]

Is your feature request related to a problem?

I have a fanless mini pc on N5105 chip, I would like to use it as a small media/streaming/light gaming device connected to my TV. It doesn't support properly GPU passtrough via VFIO, but I can get sound from unraid sound-driver https://github.com/ich777/unraid-sound-driver
However what I tried I can't get sound in the container to work.

What is your feature request?

Please add audio passthrough to be used on HDMI output.

Are there any workarounds?

To @Josh5 : There are manuals to do this in the x11docker wiki. I started off my project in 2020 from there.

I was playing around with this a few months ago. I got it working after some time. Since then I didn't have a proper setup to do some further testing. I will upload a cleaned documentation of my steps and I would love to get this tested and implemented at a later point. Which OS are you running?

Perfect. Same is true for me.
When I cleaned the docs I will report back and hope we will get this working. Can you please give me some more informations on your system. Gpu(s), unraid version, anything you already did trying to get this working...

I tried getting it working about 12 months ago but gave up and just went back to a VM, can't remember what I tried back then.

I have 2 GPUs I can test with, an Intel UHD 750 & an RTX 3090. Unraid version is 6.12.10

I have 2 configs
One is that has VFIO working it's an i5-6600 with r9 270, well windows in vm works, I don't remember trying to get steam headless there at all.
The daily setup that I wanted to use for some retro gaming is a fanless mini pc on N5105. Unraid is cool. But I'm fine switching to another OS, as this is not a NAS in my usual understanding.
