In general, sleep is transparent to applications. It just happens. From
the HAL's perspective, it is, at worst, going to require a resynch with
the hardware. (This normally shows up as one or more overload
notifications from the HAL.)
Without more information, it's going to be hard to pinpoint what the
trouble might be. I'd start debugging this by looking at what exactly
is happenning at sleep and wake up. Try throwing some printf's around
to log what your code is doing across the break. Pay particular
attention to what notifications you are getting from the HAL and how
you are reacting to them.

Hi,
I have a simple application here that just passes data recorded on the
microphone input to the speaker output. All works fine, but after
suspend mode the application does not work anymore. Any idea why this
happen. Do I have to reinitialize anything after coming back from
suspend? Ho do I get informed about that?
I use 10.2.8 on a new iMac.
Thanks,
Peter
