A sound card line input is typically abut 300mV and 10 - 47k so rather a mismatch! A DI box might not help much unless it specifically has a high impedance input and has around 20dB of gain. Sometimes you can cheat by putting a resistor (470k - 1M) in series with a microphone input, but it will tend to be rather noisy. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
