But now I have a super fast i7 laptop with loads of RAM, an SSD C drive, and a fast USB external drive to record and playback from, with windows 7, and a MobilePre and now I get that noise at 128 samples. If I switch to 256 then it is fine. I am using it at 48khz too.. but it hasn't occurred to me to try changing to 44khz, so i will try that tonight.
I couldn't find a fix for it sorry man, I had to sell it in the end to someone who owned a MAC.
Mine only worked at 44.1, 256 samples. NOTHING else worked without distortion. It must have been the drivers causing the problem, Windows 7 should not have been qualified by M-Audio on this one as it simply didn't work.
I bought a Focusrite 2i2 in the end to replace it, it's lovely looking but it could do with some more gain on the pre-amps just like the Mobile Pre.
Hope this clears things up a bit.
