[chuck-users] OSX updates =< real-time audio?

[Ge Wang]

Greetings,

We are experiencing some rather unfriendly real-time behavior on
OS X, seemingly after doing the latest apple upgrades... here are 
some details, at least on my machine:

* system: Macbook Pro / OS X (10.4.11)
* updates: Quicktime 7.4.5 + MPB EFI Firmware Update 1.5
* symptoms: real-time audio "goes to poop", even under moderate
   loads. 
* workaround: running command line chuck in BLOCKING mode (via 
--blocking) seems to work, however the default CALLBACK mode seems 
completely hosed, even with bigger buffer sizes.  This is especially 
problematic for the miniAudicle, which doesn't have the option currently 
to choose between blocking vs. callback.

Has anyone else noticed similar behavior, either on Tiger or Leopard?
Or is this an isolated case for my system?  We'd appreciate any input!

Thanks!!

Best,
Ge!
