Hi,
(Thanks to Jeff and others for their help).
I am more than satisfied with CoreAudio ability to run Audio I/O with
very high priority. Using PCI audio cards, there are no clicks up to
98% CPU load (menus and windows open several minutes in this case). But
there is a serious problem with USB and (I was surprised) FireWire.
When the CPU is loaded to more than 70%, there are dropouts and clicks.
It must be something with higher priority than USB/FireWire, but lower
than audio, blocking I/O. What is this? Is there a possibility to give
this thread greater priority? It seems to be a general I/O thread,
isn't it?
Thanks
Lubor, DSound
