Excessive Processor Usage: Avid 002 & 003 Family Driver

[Mike Harrison]

After replacing the older Digi CoreAudio driver (v9) with the Avid 002 & 003 Family driver (v11), there is excessive processor usage and processor temperature when launching audio software that accesses the driver.

I first noticed it using Adobe Audition. Without even having an audio file open, processor usage leaps to and remains at about 70%, as does the processor temperature, to 65°C or higher. Then I launched Pro Tools (LE 8.0.5) and saw the same conditions. And the same is also true when a web browser grabs the Avid driver for online audio.

Apple's Activity Monitor utility shows a kernel_task causing this. That's all I can say; I don't have the knowledge to research this any further, but I am told by those far more experienced than I that continued processor use at high temperatures will definitely shorten its life.

I hope that someone from Avid will look into this. My system specs are Mac OS 10.8.3, Processor: 2.5 GHz Intel Core i5, Memory: 16GB 1600 MHz DDR3. I had been successful running Pro Tools LE 8.0.5 and Adobe Audition CS6 on this computer with the Digi CoreAudio driver ver 9, but it acted erratically (it would self-launch if I merely opened a Finder window containing audio files and would keep relaunching if I quit it, and it would cause freezes if I attempted to play standalone or online movies.

Hello! Same problem here, but I thought it caused by that I'm using Hackintosh instead of Mac. If it is the same on real Mac than it must be drivers - does driver version 9 works under Mountain Lion? Cause I tried to install previous 10 version and it failed to work

Installed 9r3 Drivers, works not bad, at least CPU isn't loaded so much (but problems with outputing system souns and application sound such as browser)
