I have a Audiophile 2496, and if I capture in Gigastudio at 24bit/44.1...everything is cool...I can open it in Sound Forge and convert to 16 for CD...no problem.
If however I set the Audiophile and Gigastudio to capture in anything above 44.1...it ends up all funky when I listen to the recording...faster and higher. What am I doing wrong. Whatever I set Gigastudio to capture in...it automatically shows up as that setting in the M-Audio control panel.
If I convert or resample the funny sounding recording, it still sounds messed up.
Btw - are you sure your drivers are up to date? This sounds like heavy aliasing distortion or something like that.
I had something like this when bouncing in GS3 using my old Terratec card with GSIF1 drivers.
