Reply to 1 year with clipping TP/S2 issues

Ever since one of the releases (pre 2.5) I fell victim to the high-CPU / audio clipping bug. Never since then has Traktor worked properly. I've had a couple shows where I had horrible clipping.

If I disconnect the S2, CPU utilization goes way down. I still don't feel this is a hardware issue, it's all attributable to one of the updates from a while back, and none of the fixes have worked since.

Thoughts?
