hello,
Is there a known issue with the siInterrupt?
Under 9.2.1 it's working as described in IM
and the Carbon docs as far as I can tell.
On X with Carbon it's not. I'm using it to
drive my realtime sound processing program,
actually it's the central part I'm afraid.
A little inspection with an up-counter routine
installed, shows it is triggered only once,
further investigation shows the samplebuffer
size parameter, given to the interrupt is 1(one).
Under 9.2.1 its just ticking away and the sample
buffer size corresponds to the internal buffer size
(16384 VM on, 2048 VM off), I'm providing no
buffer to the SPB, but process and copy the raw
samples myself.
The siCompletion and the playcallback are
working and the rest of the Carbon soundin
routines I use, are ok on 10.1 AFAIK.
hope someone has some information on this
many regards
