Leopard and Audio Stutter Requiring Restart

Question

Ever since installing Leopard, there will be some random event that causes audio to start stuttering and the only way to stop it is to restart the computer. I use Guitar Rig 2 very heavily but it isn't just the tracks with GR2 active that stutter. Once it goes, it's all the way gone and affects all audio. I normally use headphones and can sometimes go two hours before it fails but it doesn't seem to survive more than five or ten minutes when I'm using the monitors hanging from the audio interface. That kind of points to Presonus incompatibility but the best course of action is not at all clear. Any help would be appreciated as a back-out would be next to impossible.

Answer 1

I finally have a chance to get back and check Q&As/Posts. I actually solved my stuttering, indirectly thru another issue. During the 10.4 OS update, my dock (in Leopard screen) dissappeared. In the attempts to recover it, I fell back on my PC way of thinking and decided to re-install the 10.4 update, and wa-lah, the dock was back, and the stutter stopped and has not returned to this day. It appears the updates could have something to do with it, in addition to, things like a cell phone near by, frequency interference from other electronics, etc. However, I still think it's often an update related matter.
Here's a discussion on the issue, and also do a search in support with "Macbook audio stutter" and do the search for the last 90 days. The search will yield some good discussions, even more relevant ones the last 30 days, one person noting stuttering started after their upgrade to 10.5
Hope this helps.
