newbie question: activateAudioEngine failure consequences

Apologies if members see this post twice, but I had sent my question a day
ago, and it never reached the list.

Hello. I'm a complete newbie to coreaudio, and I have a simple question,
whose answer I cannot find in the documentation. Perhaps it's very basic.
When a call of activateAudioEngine fails, what action beyond a call to
release() is necessary? I'm finding that I cannot unload my driver after
this occurrence, because myAudioEngine->free() is never called (although my
audio device is freed). I'm not sure that I have a right to call a double
release(), or the system may panic. The simple PCI audio driver sample does
not check the return value of activateAudioEngine.

Does anyone have an answer to this?

thanks,

Philip Lukidis
