I have run into a curious problem with a particular plug-in.
I call kAudioUnitProperty_SupportedNumChannels to get the supported
channel info on this plug-in and I clearly get this array: 0000 0002
0001 0002 0002 0002
Meaning to me that it accepts 0 in 2 out, 1 in 2 out and 2 in 2 out.
However in Auval all I see is:
FORMAT TESTS:
Input/Output Channel Handling:
1-1 1-2 1-4 1-5 2-2 2-4 2-5 4-4 4-5
5-5 5-2 6-6 8-8
X X
In other words AUVal does not see the 0 in 2 out. Also the problem I
am having is that if I set the plug-in to 0 in 2 out it will not
accept it and sets its input number back to 2.
Any help appreciated here.
Note that AULab does not show 0 inputs as a possible configuration
either.
Note also that I am using a very old version of AUVal 1.1b9 I think
since others I have seem to have expired.
