M-Audio Fast Track USB recording delay / out of synch

[tigerflystudio]

Hi, I have been trying to use the M-Audio fast track USB to record guitar on my PC. After downloading the latest drivers from M-Audio's website (for Vista 32 bit SP1) I tried doing a few recordings.

The problem: I am hearing the audio from the PC fine, and I am hearing my guitar perfectly fine and in synch. But when I listen back to the recoridng, it is out of time with the first track.

I wondered if it might be a latency issue? (Although I am hearing everything in synch whilst recording - it's only upon play-back that the newest 'take' seems to have recorded slightly too slowly (delayed).

I changed the latency sllider in the Fast-Track menu (which seems to be the only slider there is in that menu) from 256 to 128 and then re-recorded some guitar. I noted (after a rather long-winded test) that the first recording (256) was delayed by 53ms. The second recording (128) was 48ms delayed.

Any ideas on how to cure this? I'm new to PC recording and this is really doingy head in.
