SO I was dealing with the audio routing issue, which I THINK I fixed finally? However I have an HDMI switch that has the MAIN PC hdmi AND the consoles switch's HDMI plugged in to connect to the capture card's HDMI IN (Avermedia GC573). So whenever I turn on a console, the hdmi switch breaks connection with my main PC and only the consoles switch is connected to the capture card. I apparently cannot connect both consoles and MAIN PC at once.
Do I need a different HDMI switch or do I need to buy an HDMI splitter in this case?
What I'm trying to do is connect everything to the capture card on the streaming PC so I can keep all of my audio from the main pc while also being able to catch any game console footage as well if I choose to play something on the ps5 for example
