If you are using multiple outs from synths you are effected. I know I am. Another thing to do is disable arm monitoring during playback/record.
I suspect Cakewalk will be supplying a regression release soon. If issue persists after that I guess standard troubleshooting procedures can commence.
The standard advice otherwise is to update firmware/drivers of your audio interface. Goto intel driver update website to update chipset drivers, and probably update your motherboard BIOS.
