That makes far too much sense! Thanks...

Hi all,
This may seem pretty basic, but when I open the
kAudioUnitSubType_DefaultOutput (or open the
kAudioUnitSubType_HALOutput and connect it to a device), what is the
best way to query for the maximum number of channels supported? That
is, if the Digi 002r is the default output, can I query the default
output AU, and find the maximum number of channels (which would be 10
for the 002r)? The kAudioUnitProperty_StreamFormat doesn't give me
the maximum, just what seems to be the current settings for the
output.
Thanks, Tom
If you ask for the stream format for element 0, *output* scope, you
should get the total number of channels. If you ask for it on *input*
scope, you'll get whatever you last set as your client format, or the
default.
