XIOAudioControl is the name of the C++ class in the implementation of the
HAL that manages its dealings with IOAudioControl objects in the driver.
However, it does not have a method named MachoCallBack in it. It does have a
method named MachPortCallBack, though. Are you sure you are reading this
right?
At any rate, this is the method called when the driver sends a message to
the mach port the HAL has told it to use for a particular IOAudioControl via
IOConnectSetNotificationPort(). This usually happens when the value of the
control changes.
Can you give us any more details about the crash?
