    Hey,

    What audio interface are you using? If some form of Avid/Pro Tools interface make sure you have the latest driver(s) installed. Also, make sure you match the sampling rate in the Mac AudioMidi utility to your timeline sample rate.

    I was getting this last week but have not gotten it after doing the above and a COLD BOOT. I also updated to 6.5 yesterday and so far have not seen the issue but I have not played a timeline much yet with 6.5 .

    A Cold Boot means shutting the system completely down (not just restart), count to 10 and the boot the system. Booting to safe mode is also a good idea to clean caches, then boot normally.

    I answered this in another forum, was that you?

    Good Luck,
    Robert A. Ober
