I'm having exactly the same issue with Live 8.3.4 on my Mac using a M-Audio Fast Track Pro, but I can't turn the monitor option to 'off' as I need to be able to hear the audio output from the microphone (I DJ on an internet radio station and hence need to be able to hear all audio output from Live).

    It's as if I'm hearing the mic input and the mic output almost simultaneously, but with just a minute delay in output timing, hence causing an almost chorus effect in my vocals. I can add a small delay to the vocal track and that gets rid of the chorus effect but also severely puts me off! I've made sure the mix knob on the Fast Track Pro is set to playback, and altered driver error compensation, buffer size etc but to no avail. Anyone have any further thoughts?
