auval problem for mono-only plug-in

Hi all,

I'm getting a failure of the mono version of a plug-in in auval.  I don't see why it's failing.  I'm getting the following in auval:

VERIFYING DEFAULT SCOPE FORMATS:
Input Scope Bus Configuration:
Default Bus Count:1
    Default Format: AudioStreamBasicDescription:  2 ch,  44100 Hz, 'lpcm' (0x0000002B) 32-bit big-endian float, deinterleaved

Output Scope Bus Configuration:
Default Bus Count:1
    Default Format: AudioStreamBasicDescription:  2 ch,  44100 Hz, 'lpcm' (0x0000002B) 32-bit big-endian float, deinterleaved

HAM: SupportedNumChannels set is 1 in, 1 out
HAM: SupportedNumChannels returns 1
HAM: SupportedNumChannels set is 1 in, 1 out
HAM: SupportedNumChannels returns 1
HAM: SupportedNumChannels set is 1 in, 1 out
HAM: SupportedNumChannels returns 1
HAM: SupportedNumChannels set is 1 in, 1 out
HAM: SupportedNumChannels returns 1
ERROR: Default Format of unit does not match reported Channel handling capabilities
* * FAIL

The "HAM" outputs are mine, and are coming from SupportedNumChannels().  As the outputs show, I'm setting the ChannelInfo to {1,1}, and returning 1 from the function.  So it should only be reporting 1 in, 1 out as the valid setup.  Where does the "Default Format" come from, if not there?

In the ValidFormat() function, I'm rejecting anything which doesn't have 1 as the number of channels per frame(and the output shows that, later, as well).

I'm confused as to what's telling auval that the "default format" is 2 channels???  Anyone know where I should be looking?

Thanks,
Howard
