I have the problem, too.
Dell Optiplex 760
Intel Core 2 E8400, 3gHz, 3 gig ram
32 bit Win7
Juli@ card
BBP ASIO 0.90.95
In Phase Linear mode, I get 2 to 3 days before the audio clicks, spits or burps… it’s pretty random, but obviously wrong. CPU load goes over 88% at its worst
For me, the fix is as easy as hitting the IO Config tab, "yes", & "finish". The processor returns to normal & CPU load drops to 15 – 20%.
