Hi
I already sent this question to the Apple list 1 month ago,
and i received two answers from Eric Brown and Jeff Moore.
From Eric:
"There is an extra retain being held on the driver class by one of the
user-land applications. The driver will unload if you log out and then
log back in again. That causes the naughty app to quick.
Alternatively, if you do your testing from the text console, you won't
see the problem."
"It turns out it is caused a bug in
the shipping CoreAudio.framework, so any app that makes sounds or
watches for audio devices trips over it. Unfortunately that includes
the loginwindow process (which is why you have to log out). I believe
this is scheduled to be fixed in the next release."
From Jeff Moore:
"This is a known problem. The work around is to unload the driver from
the console. It's a pain in the butt, but it only comes up if you're
doing driver development."

Subject: Audio Drivers unloading
Hi.
I am developping an audio driver and I can't unload the driver unless I
logout and relogin.
I always get the message :
Can't unload com.airy.driver.AudioDriver due to -
com.airy.driver.AudioDriver: com_airy_driver_AudioEngine has 1
instance(s)
Did I forgot anything in my code ?
Airy
