| Hi,
I'm still working on my AC3 encoder driver, and was attempting to use kAudioStreamPropertyTerminalType to find SPDIF interfaces attached to my Mac. I was expecting it to return a value as defined in AudioHardware.h, ie kAudioStreamTerminalTypeDigitalAudioInterface or similar. However, after checking the HALLab source, I find it returns a terminal define in IOKit's AudioTypes.h. This works just as well, but I was wondering what the point of having the various terminal type defines in AudioHardware.h was, particularly as the header suggests these are returned when the terminal type is queried.
Regards,
Ryan |
