So I recently decided to start streaming on twitch and have decided to do a 2 PC setup. Well I watch a very good tutorial on how to get it set up properly and I have Spotify running through its own virtual cable (cable B), also changed the app output to that as well in windows sound settings, but I keep getting Spotify coming through my Elgato as well as the virtual cable lane. It causes a double sound on stream. If anyone can help that would be great! Thanks!
