USB Soundcards - faint popping/clicks


I am currently using a G4 iBook 933 MHz and have my new Waveterminal U24 connected to a DAC and Headphone Amplifier. The sound is really fantastic. I do notice every minute or so, I get a very faint pop or click sound. Sometimes I go longer without hearing it, but it occurs often enough that I notice it. I have tried to research this and there seems to be an opinion that this is just a USB audio problem and nothing can be done. I have experimented with settings. I have more than enough RAM than I know what to do with. I am using iTunes and so there really aren't any settings to adjust there except turning off all of the enhancements.

Anyway, anybody have any suggestions for USB audio pops?

This is a buffering/cacheing problem. You should try different buffer size settings and latency settings if you have those available. If you are using iTunes player these usually go away. They can occur with Foobar2000.
If you defrag the disk and kill all other applications except the player, you should not get pops and ticks. I was getting pops and then they went away after I defragged. After I installed Turbotax and left it running, the pops came back.
