In that case, you are likely hitting the MACH_SEND_INVALID_DEST error
as the "call" to the driver to start the hardware is really a mach
message. The fork probably left your mach port names a mess in the
child process without the exec.

Thanks, interesting.
I'm doing the AudioDeviceStart in a forked process, where previously
it had been done in an exec'd process.

Hello,
I'm getting an error code:
0x10000003
from AudioDeviceStart. I can't find this code in
AudioHardware.h, so
it must be a more general error.
Any ideas what this might be?
[/usr/include/mach]$ grep -r 10000003 .
./arm/processor_info.h:#define PROCESSOR_CPU_STAT
0x10000003 /*
Low level cpu statistics */
./message.h:#define MACH_SEND_INVALID_DEST 0x10000003
