To do my radio LiVECast tonight, I require Stereo Mix to work with my Realtek HD Audio Driver. I had it all sorted, but when I got onto skype to start a test cast with one of the people featuring on the show, I found my Recording (NOT PLAYBACK) volume started to decline. I disabled Stereo Mix and it worked again. I just don't know what to do, I don't want to let my friends down because it's an end of year event D: Any suggestions on what I could possibly do? I've updated my drivers but that did absolutely nothing.
