Hi,
searched around and found an archive discussion which was talking about
this mainly from the Sound Manager point of view.
But looking at PlayAudioFileLite, it use the component manager to find the
Audio Unit to send the sound out of, but it uses kAudioUnitType_Output, but
listing these, don't show
Builtin Built in Audio
Digital Out Optical digital output
Speaker USB
But show what look equivalents of the kSoundOutputDeviceType. Sorry but
not making any understand of how to get the above information, as I need to
be able to direct my sounds to one of those outputs
Thanks advance for some pointers, as I'm still on the learning ramp here.
Mark.

Hi,
Looking at the same code on G5 Tower, my Sound system preferences lists
internal speaker and digital line out, and Apple USB speakers, but the below
listing is still the same, as I'm listing the kSoundOutputDeviceType.
so I'm guess this isn't the right way to go about getting the possible
output devices ???, or is it, as I understood that this is what you are
suppose to use ???.
How are you suppose to do this correctly,
Thanks
Mark.

Hi,
I was playing with some code listing the output sound components of my 17"
portable, but I was surprise that I had 4 output components
1) <no name given>
2) Firewire DV
3) Mac OS X Audio Hal
4) Mac OS X Audio Hal (System).
What are the difference in these ???, and as I only have the internal
speakers which appear in the sound preference I'm surprised I get all these
Can anybody shed some light on this.
Thanks
Mark.
