Problem with USB audio

About a week ago, when I tried to play music using my Asus A8 laptop and Benchmark DAC1 USB, music would play for a few seconds, and then drop out completely after a sudden, unpleasant noise, regardless of whether I am doing anything with the laptop or not.

I used my Asus laptop, which was less than two years old, to feed data to the Benchmark DAC1 USB via a USB cable. Before last week, I had no problem with USB audio at all - even when I am doing many things on my laptop at the same time. I have tried an IBM PC and a Macbook Pro after the problem arose, and they both worked fine, so the DAC1 USB and the USB cable are cleared. I use Foobar 2000 v0.9.5.6; however, I also tried Windows Media Player, with the same result - after a few seconds of music, the music stopped completely while the WMP indicates the music was still playing (like Foobar did).

So, apparently there's something my laptop was doing wrong, does anyone know what? Any comment/advice is greatly appreciated!

Make sure that the USB port on your computer is a good one. Try them all.

Also, give the player high priority - realtime or highest.

If you are running any other USB devices, this will screw things up. Remove them and try again. You may have a conflict in interrupt servicing.

It is a documented and well known fact that there are differences in USB ports on various computers - Macs and PC alike. Try them all as Steve says.
