4.0 and Sonar a dual core disaster... for me

[Axiology]

3.9 works fine on my AMD dual core machine, but 4.0 is a mass of pops, clicks and gravel. Nothing I do seems to help. It's the same in Sonar 4.03, 4.04 and 5. I've tried everything I can think of, changing PCI slots, PCI and buffer settings on the UAD configuration(reseting the Sonar audio engine with each change), DMA buffer settings for the Delta 1010, different delta 1010 drivers, Sonar latency and wave profiler and probably a few more things I can't think of right now. Seems to me 3.9 supports dual core but 4.0 does not......
Anyone got any ideas?

thanks

But I have found a solution I can live with while I'm waiting for an optimal solution: Turn off hyperthreading or turn off fastbounce when you freeze tracks or bounce tracks or export audio...

If you are running XP Pro SP2, check out Microsoft Article 896256. It may be of interest to you.

I've already installed the hotfix with no result regarding my problems... :?
