I have a brand new iMac running MC 7.0.3. I've been working on it for about a week and have noticed that the there is sluggishness in the audio. Everytime I stop playback I hear what sounds like a reapeat of the last frame of audio. It seems like Composer is having a hard time stopping the audio in a frame-accurate way. The same thing when I'm scrubbing if I move quickly frame by I hear every frame being repeated. It's annoying and I think it may be causing other audio issues for me (like with Blackmagic). Anybody have this problem or know some trouble shooting I might do? Very frustrating for a new system with plenty of RAM and speed to not work perfectly.
Thanks.
