Sound error when vinyl control on/off

Hello, ive noticed this since Ive upgraded to 7.214.
Before, ive noticed it few times...1x of maybe 7 "off turnings"....
this problem risen since update to 90%... so allmost every time i turn vinyl control off the sound makes "DRRRRRRRRRRR" for like 3 sec and then continues playing...
Runing on XP SP2, 1.6 celeron 1gig Ram...
some suggestions?
