[chuck-users] mac intel audio i/o problem

[Gregory Brown]

I am also getting strange [new] messages on my new MacBookPro running  
1.2.0.7. The script ran without any problems running 1.2.0.6 on my  
old laptop, but has started giving the following on the new machine:

I don't know if it is related, but it is new with the new system. I
