I’ve recently migrated from a raspberry pi 4b to a dell Optiplex running Proxmox and I’m having a lot of fun with it.

One of the services I have running is Raspotify, which allowed me to plug my pi into a speaker and run Spotify through it.

I had a quick go passing the audio jack through to my HA VM and it just stopped working completely. Only after removing the pass-through did it work again.

So if anyone has managed it, what do? Do I use SPICE as a driver or none? Which device is it?

Thanks

    Hmmm… I do have audio coming out of a guest VM under proxmox, but I’m passing through a whole GPU which includes audio through its HDMI.

    The on-board audio might not be in an iommu group that can be passed without breaking something else, which would likely prevent booting the host correctly.

    Honestly, I think I’d just go with a USB dongle for the audio. Easier to passthrough, likely better audio quality too and shouldn’t be too expensive.
    You can pass either a USB device id or a port (or group of ports, depending on how it’s grouped)

      This is the easiest answer. I tried to get audio into a Guacamole VM years ago. USB adapter was the easy win. Never actually found the resource number for anything close to what i wanted.

      I hadn’t even considered that as a solution, and I’ve literally just bought a usb to 3.5mm for my main PC.

      Thanks for the idea, I’ll purchase another cable.

      I have a bloody drawer FULL of cables because I do stuff like this. To the point where I’m wondering if the meaning of life for a human male is to collect as many cables for various devices as possible before you die lol.

      Thanks for this, it totally worked although I’m not quite satisfied with the audio quality. There’s artifacts in the sound stream, like a clicking, and Ozzy sounds a little strange when I play Bark At The Moon.

      But all in all it’s better than no audio, so thank you.

      I of course tried to pass through the audio device again, don’t wanna have to spend money if I don’t have to, but it crashed Proxmox again so it was straight to Amazon.

        In my case, I think the onboard audio device is in the same group as the motherboard chipset, which would explain the host crashing when passing through.

        Also, the crackling might be something about the sampling rate. It’s been a while since since I poked around with audio, but I vaguely remember changing the default sampling rate and restart pulseaudio or something like that.
