ComplexPlayThru failure if input srate != output srate

I downloaded the ComplexPlayThru example and configured my MacBook Pro's line input device to 48kHz and the output device to 44.1kHz. I then built and ran the app and it got out of sync almost immediately and stopped producing output so that the last buffer it produced repeated over and over again. According to the code, it should handle devices with different sample rates (and it prints a message about the mismatch and that it is setting the playback rate of the AUVarispeed unit to some non-1.0 value) -- is there something missing?

Some previous posts to this list (Neil Clayton, Bill, and Jeff) indicate that the code is probably fragile with regard to handling overloads and discontinuities well. Is there a better example anywhere?

10.4.9, QT 7.1.5

thanks,
stephen
