I'm having trouble using the "M-AUDIO Fast Track Pro" USB audio interface to record with.

I've tried to manually adjust the latency in the M-AUDIO Fast Track Pro Properties but the slider is locked at 256 and won't let me adjust the value.

No matter what I try, there is a latency issue present when trying to use M-AUDIO USB Audio Interface to record properly without lag.

How can i fix this issue?

Thanks in advance

some audio interfaces wont allow the value to be adjusted if the device is in use. Are you using it with particular recording software/DAW? – richaux Aug 20 '12 at 15:29
audacity - already tried to adjust latency in there though – CheeseConQueso Aug 20 '12 at 21:59
@richaux: is it possible that, when the device is set as the system default, it is then "locked"? Should the OP check to see if the device is the primary audio device and if it is, set the other sound card as the primary? – horatio Sep 19 '12 at 21:02
@horatio, I'm not sure!! My comment was based on experience with a different M-Audio card and Cubase, whereby changes in card parameters affecting latency were not allowed when Cubase was in use (unless Cubase's "release in background" option was set). However, for my setup I was able to change the card settings freely when Cubase wasn't running, even though it was the system default. – richaux Sep 20 '12 at 8:32

Is it possible that the FTP's buffer doesn't go below 256? I remember my M-Box-1 couldn't go below 512, which was why I sold it. – Robert Dec 18 '12 at 15:22

It sounds like a driver issue, as M-Audio kit tends to have incredibly low latency. Go to their site and check out the latest ASIO drivers - you may need to reinstall them.

thanks, i did that last night but not too sure if i correctly installed and applied the ASIO drivers... can you provide more info? – CheeseConQueso Aug 19 '12 at 18:08
Did you get any improvement? – Dr Mayhem Dec 17 '12 at 17:34

The problem may be less with the hardware and more with your choice of software; Audacity isn't exactly professional-quality, and it doesn't come with ASIO support out of the box for licensing reasons. See http://wiki.audacityteam.org/wiki/ASIO_Audio_Interface for more information.

This is right. The low latency features on your Audio Interface will not really get to shine without using the ASIO drivers. – user1167442 Apr 10 at 1:21
