[M577]

Hello. Playback produces "The audio device underflowed. If this occurs
frequently, try decreasing the "H/W Buffer Size" in the Playback Engine panel or
remove other devices from the adio firewire bus. (-6085)"

my system specs are:

MacBook 2.0 GHz Intel Core 2 Duo (T7200) (MB061LL/A, white) upgraded to 2GB of
RAM and 7200 rpm hardrive

Mbox 2 Pro
OS X 10.4.9
Pro Tools LE 7.3
H/W Buffer size is at 64 samples
RTAS Processor 1 Processor
CPU Usage Limit 70%

Troubleshooting already attempted:

Mbox 2 Pro is the only device connected to my single Firewire 400 bus.

Zapped the PRAM.

Downloaded the tech support folder:

Ran support utility and used it to delete preferences and databases.

Used the Apple disk utility to repair disk permissions.

Wireless networking and bluetooth are turned off.

Just fixed this on a friend's system a few days ago. You said that you're running LE 7.3. Download the LE 7.3.1 cs6. This fixed it for him.

Here's the link for the Mac download.

Pro Tools LE 7.3.1cs6 Update for Mac OS X did not clear up my particular problem. Any advice to fix my current situation is much appreciated.
