Getting the fundamental frequency out of a signal from soundcard

(OP)
Hi

I wonder if any one have any idea how I can get the fundamental frequency out of a signal I get from the soundcard input on my computer. The signal can be a instrument. I get a signal with the help of the functions SI read, SI configure av SI start. The signal is a 8 bit mono signal with 8000kb/s sample rate, and I use a buffer of 8000kb.Hope anyone can help
