I'm using this very same card with Vegas and everything's working smooth. Did you get the latest drivers from the M-Audio site? What are your computer specs?

thanks a lot for replying. I used the drivers that came with the card. My computer is 800 mhz P3 256mb RAM. In the manual it says to minimize graphics acceleration, i tried that, still the same problem, am quite stumped and troubled about the whole thing, cos i can't make people do retakes cos of my sound card problem. what drivers did you DL?

Hi there,

I had a very similar problem with a Delta 1010 and P3 667, 512MB and it ended up being a bad RAM stick. Took me weeks to figure it out as it was very intermittent and the Norton memory testing utility I was using could not test 512MB. There are memory testing utilities available for free somewhere if you'd like to test it, or if you have more than one stick in there, try each one alone and see what happens.
All this said, I think your problem is more likely to be something else... drivers, settings.

All these interfaces ie M-Audio, Edirol, Aardvark... all take a lot of windows resources to pump 8 or so tracks of audio through the bus pipeline. Computers are digital machines and work on clock cycles, they can only handle so much. If other tasks start using the system bus or memory bus while you are recording things can get messy if there aren't enough clock cycles to handle the workload.

Causes:
-cheap motherboard
-cheap ram
-slow processor
-slow system bus speed

I suggest going to a 166 Mhz bus speed at a minimum to give you good headroom for audio. Athlon or Pentium systems run at atleast that now. Older p III's are still sitting at 66 or 100 Mhz.
