I can no longer use the MXO2 mini with Media Composer 5.5.2
Upon launching Media composer, when the load gets to the audio drivers I get an Avid message that says "can't initialize audio hardware" which then brings up another message which says segmentation fault in thread Main thread at address 0X0. Media Composer than crashes to the desktop.
If I turn off the MXO2 mini, Media Composer launches perfectly.
Also the MXO2 mini works fine with FCP 7.

I have uninstalled Media Composer and the Matrox software numerous times,
always with the same results.

I am running Mac OS 10.6.7 using Media Composer 5.5.2 and using Matrox software version 2.2.3. Also using FCP 7.0.3

Any help would be greatly appreciated.

I would suggest first trying a manual uninstall of the Matrox driver; then reinstalling.

Here is the procedure:

1. Uninstall current Matrox driver using the Matrox uninstaller application found in Applications->Matrox MXO2 Utilities-> Matrox MAX Software Uninstaller

2. After the system restarts, follow the *** Manual Verification of Uninstall *** procedure listed below.

3. Run a MAC software update making sure to update any EFI firmware revisions and pro applications updates

For Final Cut Pro/Compressor users (steps 4 & 5):
4. Run the Preference Manager utility to clear the final cut suite preferences:
Link: http://www.digitalrebellion.com -> Products -> Preference Manager

Install and run the software, then click the default profile name in the list of profiles, then click the trash button (bottom left of window) to clear preferences. Note that this will reset all preferences to defaults)

5. MAX users only: This step removes the Matrox Compressor presets manually.

Navigate to the following folder: *user name*/library/applications support/compressor/

Look for the Matrox H.264 folder. If it is not there, that's ok, proceed to the next step. If you have made your own custom presets in this folder and don't wish to lose them, then please back them up first. Then, delete the Matrox H.264 folder. This will clear all the Matrox presets.

Detailed explanation on how to find the folder:
- Open Finder
- click on the boot drive, expand the 'users' folder, then click on your user name
- expand the following folders: library -> applications support -> compressor
- Look for the Matrox H.264 folder and send it to trash.

6. Re-download and install your Matrox driver
Download link: http://www.matrox.com/video/en/support/downloads/

Be sure to power cycle after the MAC shut downs.
