Is it possible to have a Dual PC Setup with Gaming Laptop as Streaming PC and GoXLR?

I can’t figure out how to get the Gaming PC Audio (Desktop) onto my Streaming PC (laptop) through the GoXLR which is currently hooked up to my streaming PC. I tried watching every video tutorial and just can’t seem to get the audio working on stream. Any video recommendations or advice would be so greatly appreciated! Cheers 🍻
