The facts:
1. 5 year old Dell laptop
2. Playing with Norton Music fakebook discs
3. When I increase the number of repeats the music intermittently pauses for a second then continues.
4. Using the USB port with FG-UAUDV1-C119 adapter
5. This problem does not occur when I come out of the headset jack but the music does not sound as good as #4 above.

Any ideas? Maybe a new computer?
