Our user space driver (implementing the AudioHardwarePlugin.h API)
has some problems on Tiger. It is a kind of "wrapper" on a real audio
driver that has to redirect some calls coming from the application on a
real driver.
We are using the AudioDeviceID of the real driver and just redirect
some calls, something like :
OurPlugIn::DeviceGetProperty(...)
{
....
OSStatus err = AudioDeviceGetProperty(fReadDriver_
AudioDeviceID,......);
....
}
This was perfectly working on Jaguar and Panther, but on Tiger the
AudioDeviceGetProperty now returns a kAudioHardwareBadDeviceError code,
although the AudioDeviceID value seems perfectly correct.
Any idea?
Thanks
Stephane Letz
