Host or Plugin problem?

Hello,

I have a problem with a specific plug-in that passes auval. It is a music device that does not support kAudioUnitProperty_SupportedNumChannels. My understanding was that therefore it may or may not be able to take arbitrary in and out configurations, thus I try to configure it to 0 in and 8 out for my particular application. Using kAudioUnitProperty_StreamFormat to set its format to 0,8 the audiounit returns with no error. AudioUnitInitialize similarly returns with no error. However when asked to render, the plug-in returns kAudioUnitErr_FormatNotSupported. I am fairly certain that 0,8 is not a supported configuration. Should not the plug-in be returning an error earlier in either kAudioUnitProperty_StreamFormat or AudioUnitInitialize?

Thanks,

Jeremy
