When I plug my mixer in the line in (or microphone) on my Vista PC the level meter displays that I have sound through, and I am also enable to record using "Sound Recorder". BUT I can't hear a thing until I playback the recorded sound. This also means that I have no sound when I try to use other recording applications, and ofcourse I have to hear what I play on my guitar while playing. Not afterwords.
I have checked and double checked that the line in is activated and that there is connection, but I can't hear the sound "live".
