I have my PS4 (and not only) connected to my gaming laptop to pass through the audio. Unfortunately few days ago when I was half asleep, I remember doing something, just not what, and now I don't have audio from the console (any console) passing through. When I say I did something I mean in Windows (8.1), some setting, I just can't for the life of me remember. I checked the volume mixer and the line in at rear panel is not muted. I can't see any device blocked or muted elsewhere and I can't afford to get myself hypnotized to remember what I did that day. Any suggestions?
