Multiple HALAOUs don't get along?

Hi,

I wanted to use the HAL AudioOutputUnit to allow audio to pass through a filter, to the output. However, Bill said that I can only have one device per AU (currently). So I created two AUs, one for input, and one for output. However, that doesn't work, for either internal or external input (ie doesn't work at all).

So what is the simplest approach I can take to pass audio from a USB mic, through a filter, and back out the speakers, in real time?

Thanks,
-Chilton
