scream VS Single-GPU-Passthrough

Not sure about NixOS specifically, but I'm pretty sure Scream is the widely accepted audio passthrough solution for Windows VMs.

I had a situation where there was a lot of noise on any usb connection from my PC to my DAC, but no noise on the usb from my jetson nano (similar to a raspberry pi). I set up a wireless audio interface between them using a project called Scream, so I could play audio on my PC and have it come out the usb port of the jetson. It creates a virtual sound card on the windows side, meaning you can send any/all audio from any source on the pc, which I think is what you're looking for. Warning, it was a pretty involved process and the final results were imperfect, it worked great 99% of the time but had weird pops and stutters 1% of the time.

Have you tried scream (with or without IVSHMEM)?

Hello all. I'm trying to send audio from my windows desktop pc to my linux mint laptop over an ethernet cable connected betwen the two machines as I don't have a router near them (I'm using wifi in both). I found this SCREAM tool to take the audio from the windows pc to the network but I'm not a networks expert at all. I wanna know if what I'm trying to do is even possible and if so, how can I set my linux to get the audio and play it on my headphones. Thanks.

Solved with Scream https://github.com/duncanthrax/scream

So thats really strange, so maybe try Scream audio it's on github with documentation https://github.com/duncanthrax/scream

How does connecting sound in pulseaudio compare to scream?

Yes but that's a different kettle of fish. You then don't need two gpus, although if you do it can be useful. Start here and see how deep the rabbit hole goes https://github.com/joeknock90/Single-GPU-Passthrough

Im assuming you're on a single gpu setup and, as such are trying to do single gpu passthrough with a single nvidia card. so you'll likely have to run some libvirt hooks or smth to run scripts to unbind your gpu once you start your vm. In which case id suggest going through these two guides 1 2 which go over completely passing through your single gpu when you start your vm

Out of curiosity, who is Muta, the video dude, or the guide writer, or someone else? From the GitHub it sounded like running the commands from the guide would create a qemu.d/[VM Name]/prepare/begin/start.sh . If I were to simply create those directories myself, and then script as described in the video, I should be good?

Thanks for the info. Some of these I recognize from a single gpu passthrough project on github that i used on my main rig... https://github.com/joeknock90/Single-GPU-Passthrough
