Hi,

I am looking at the /Developer/Examples/CoreAudio/HAL/AudioThru/ example that allows to make an audio thru from one CoreAudio device to another CoreAudio device.

What happens if the 2 devices are actually from 2 different audio cards that do not run at the exact same sample rate because of difference in hardware clocks?

Does the HAL contains a system able to compensate any clock drift differences between the two different devices in this case?

Thanks

Stephane Letz
