Pre Sonus Studio One Professional. But it shouldn't matter what program I'm using as it affects system sounds, MP3s in VLC player, everything! :s

im just confused. Where are you changing the bit/sample rate then? There are no settings like that on the M-Audio. In fact, I just read that it always processes incoming signal at 24bit/48kHz rate.

Oh sorry I mis-understood, there's a driver for the interface which you download and install from the AVID website. It juts adds a page to control panel where you can change input levels, SR, and latency via a grey pop up box.

Hi,

Did you solve your problem?

I get the same daleks type sound when I use anything below 256 samples on Pro Tools. I used to use it on my old computer on XP, with an older PT and older audio interface (mbox 1) at 128 samples with no problem.

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.

cheers

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.
