To test for this problem on your system, download the DPC checker at:
http://www.thesycon.de/deu/latency_check.shtml

Note that it takes a lot of latency to cause an audio problem. Well-written
drivers and interrupt handlers may cause some latency, but not enough to
make an audible click. However, not every piece of software is well-written.
For an informative explanation, see the post by "aj" at:

The instruction .pdf that comes with the latency checker has additional
useful info.

If you have problems due to DPCs, you can disable drivers, services and
programs one by one until you find the culprit.

It is a time-honored tradition to fault the operating system for problems
caused by non-OS software, and this topic is a rich lode of such misplaced
blame.
