Well, I'm not too sure about YOUR problem, but maybe this will give you some ideas. While running music, I also run Net Stumbler (as finding free internet is ALWAYS a plus). I can tell when net stumbler finds a source and what the signal strength is via the audio output. It uses MIDI audio which has a seperate volume control in the sound control pannel. thus, I keep the music a a reasonable level and set the MIDI volume slightly lower so that it can easily be ignored when I really don't care, or if I'm paying attention can easily be detected. It sounds to me that what you're really looking for is a similar setup for 2 standard audio outputs. Other than the basic premise, I'm sorry to say I can't be much more help.
