Hi Apocalyse Boy,
Your setup sounds great and would be perfect for the addition of some Raspberry Pi’s. However, we cannot guarantee that the USB sound card works. We do have an option for USB sound cards that activates the default driver for it and works with a lot of users‘ setups. You can find it in the Raspberry Settings. Just test it out 😉
We would also love to see your build, currently the images are not displaying.
