Im using onboard (realtek) sound, with driver mode = WASAPI shared 44.1.
This has always worked fine, but after this update, I hear constant distortion/crackle/noise.
I noticed if I set the sampling rate to 48k, it plays fine though.
EDIT: Even stranger... the distortion is only on tracks with FX (Pro channel, VST, VSTi). Audio tracks without FX are fine
EDIT 2: I reverted back to 2019.09 and everything is good again
