I recently bought a Klipsch R-100sw subwoofer. I connected it to my computer and it sounds amazing. Only one problem, I can’t get my subwoofer and speakers to play at the same time. I’ve went into audio device manager and enabled stereo mix but that didn’t work. I can only play my subwoofer by itself or my speakers by there self. My speakers are “black web” but I don’t know the exact model. If anyone could help me that would be great! I thought I might have to buy Klipsch speakers but before doing that I want to see if anyone can help me.
