I use Console Emulation on (essentially) all my projects.... I'm not experiencing any such issue...
From Brando : "If you are using stereo tracks exclusively with the console emu's I don't think you'll get the hum [buzz]. If you have mono tracks with console emu enabled, turn off 64 bit DP engine is the work around."
From brundlefly : "Yes, this appears to solve the problem, but only after the project is reloaded with Double Precision disabled. Enabling Double Precision will precipitate the problem immediately (on some tracks), but disabling it requires a reload for the "cure" to take effect."
