Tiny "pop" noise when play 88.2khz music

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Playing 24bit, 88.2khz flac music.

What is the expected output? What do you see instead?
The is very very tiny noise.  Like a very small "pop" sound, the time when this 
sound happen doesn't seems to be consistent.  But they always happen.

What version of the product are you using? On what operating system?
0.9.5

Not sure if it is relavent, but switching to another USB port does NOT help.  
When playing with VLC player, there is no such issue.

I saw some people use BitPerfect has similar problem, and it is solve when they 
enable "Use Maximum Device Buffer Size".  Do Audirvana has similar feature?

Upsampling everything to my dac max sampling rate "solves" the problem...  A 
bit disappointing
