If you are trying to debug something in your driver, you can use the
telemetry in HALLab to see the error being returned to the HAL. It
will show up as one of the data points to the telemetry event that
marks the return from the kernel trap.
Only the input clip routine errors will show up. The error on the
output side is swallowed up by IOAudioFamily. I wrote a bug on that
and it should be fixed when a new IOAudioFamily rolls out.
