channel config changed since 10.2.8?

Hello - been following this list for a while, but first posting, so hi ;)

We recently upgraded to OS10.3.5, and switched our development to XCode1.5 from CW8.3 -
Our existing code builds and runs fine with XCode, BUT, our MONO plugins (1 channel in, 1 channel out), have stopped working due to this:


AUBase.cpp:1291 AUBase::DoRender()
[...]
if(output->GetStreamFormat().NumberChannelStreams() != ioData.mNumberBuffers {
debug_string("DoRender: output stream format does not match ioData.mNumberBuffers");
return paramErr;
}
[...]


ioData.mNumberBuffers is 1 (correct)
output->GetStreamFormat().NumberChannelStreams() returns 2 (???)

stepping through our plug we always return 1in, 1out when SupportedNumChannels(const AUChannelInfo **) is called, and we always return false to ValidFormat() for any formats other than mono->mono

This worked previously, building on 10.2.8 - can anyone think of any changes to the SDK, or anything else which could cause this?!!

Many thanks,

Kieran.
