Audio IF, win 2000, DLL, Jerky signal - Ca'nt seem to get it to work

[tomerj]

???
Can't seem to get it to work.
Audio interface, the volume seems fine, signal is nice and stable on the scope. Works fine with the keyboard. Does not calibrate because the signal is all over the place.
I used a Hitec and a Futaba, and I even tried flipping the wires, with no success. The signal won't settle.
What did I do wrong?
Thanks

maybe you can try line in, or just calibrate it ,do'nt care about the jerky! calibrate it twice or more! this is i did in XP with my F4VF, and it works well, good liuck!
