User space plugin problems on Tiger

Subject: User space plugin problems on Tiger
From: Stéphane Letz <email@hidden>

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
