Sound Designers

I apologize in advance for the problems you're having. Leopard has introduced some problems with Core Audio that will take some serious engineering time to fully resolve - unfortunately that means we'll have to work with what we've got for the time being.

Hopefully I can get things to the point that it will be less painful for you.

First, try trashing the following:

com.digidesign.coreaudiomanager.plist
DAE Prefs
Digisetup.OSX

This will 'reset' any Core Audio connections to Digi hardware and may resolve some of these issues.

When using Core Audio, always launch Core Audio Manager first and make sure it shows connected before launching the application you want to use it. Sometimes it will not auto-launch due to initialization times (the hardware takes longer to initialize than Core Audio wants to wait, so it reverts to other available Core Audio hardware). There is also an issue with how Core Audio connects to the hardware under Leopard, which is why we have to rewrite the Core Audio code for it to work properly under Leopard.

There is also a known issue with Quicktime and any application that uses Quicktime, like iTunes, etc. where audio will not play properly until you toggle between 'Built-In' and Digi HW in the Sound control panel. This also will be fixed with the Core Audio update.

One other alternative that many have used to work around this is to cable the Mac audio outputs to the 'Alt Mon' in on the 002/003 to monitor through those devices, or into an open input on almost any Digi HW that doesn't have a separate monitor path (HD, for instance) to monitor while Pro Tools is open.

We understand this is painful to deal with and want to assure you we will get Core Audio back in action as soon as possible, however I want to be realistic about the time frame - as I said there will be significant engineering time involved and we're also investigating adding some new capabilities - no promises, mind you, but we want to make the next version a 'step up' if at all possible.

If you continue to have problems and have tried all the standard troubleshooting, please provide me with as much information about your system as possible - OS version, how everything is connected, version of QT/Safari/iTunes, etc. and how you're using Core Audio - for example, are you quitting Pro Tools and immediately launching the Core Audio app, does launching Core Audio Manager show 'Connected', but you're not getting output and so forth.

Please also let me know which drivers you have installed in your HAL folder located at MacHD/Library/Audio/Plug-Ins/HAL and what their version numbers are.

Users with any of the Mbox series, other than the original Mbox, should not see these issues, as they use a 'native' Core Audio driver model - which we're going to try to move to for all Digi devices with the next update to Core Audio
