Cheers for the help guys & Jiglo, I wholeheartedly agree with the laptop soundcard issue, which is why I bought a M-Audio Audiophile external soundcard a couple of years ago and was using it happily with both soundforge & in Nero Wave Editor.
Anyway, I recently swapped laptops & have downloaded drivers for the soundcard, but I can't get a signal from my mixer within soundforge, even though I have assigned the M-Audio as the main input/output device, & in Nero Wave Editor, even when on the lowest setting on my mixer, the levels are in the red.
I tried twice, rang up the help desk at M-Audio & the guy just kept on telling me to turn the input source down. I was just getting more pissed off with him, because I quite clearly couldn't reduce it anymore, because the mixer's faders were on minimum. He got peed off with me because I was telling him it was something else.
Hence the reason I want to buy something else to get me round the problem unless there is an obvious solution to my laptop problems.
