cpu maxing.. I had a few presets that did it after the update.. check cpu usage.
Too bad to hear that mister, Analog out's would a alternative, but I likes to track my DI's AES before Analog reamping.I've been getting the same since 17 - so bad that I've gone back to using the analog outs, which is a pain because I'm out of inputs on my RME UFX.
AES is hardware, firmware can't suddenly cause it to crackle. The clock source is now programmable but that's just a hardware setting. FWIW I normally use AES and it's working fine here.
