Hello. I'm having a bit of trouble setting up the audio on KVM. I want to share my device, as shown here:
https://wiki.archlinux.org/index.php/PC … PulseAudio
I've tried both the hda method and the usb method, but neither worked. The device shows up in the vm and is showing that it's outputting audio, PulseAudio just isn't picking it up. I checked in the /tmp folder for the server file I specified but was unable to find anything. I think it might be because I'm not using a usb speaker (it's an aux cord), but I'm not sure what device to use or the settings that would go with it if that is even the problem. Below is my virtual machine XML file, where you can see me attempting to connect it via a usb speaker:

So after spending hours trying to figure this out, I finally figured out what was wrong. My pulse server was located in /run/user/1000/pulse/native. I also got rid of the usb portion. For future reference, this link helped me a lot:
