Hello list-members,
i've programmed an audio driver plugin for my kernel driver of a usb
2.0 audio device. The purpose for the plugin is to save some custom
settings, so i can reload them once the kernel driver is loaded. In
the plugin i use the kAudioHardwarePropertyProcessIsMaster key to
find out if the master instance has loaded the plugin, and only then
do i load and save my settings. The problem i'm having now is that
the master instance doesn't always load the plugin. Furthermore i
can't quite figure out when it loads it and when not. Seems kind of
random to me. HALLab is telling me that there is a driver plug-in
present. And programs like Audio MIDI Setup and HALLab do load the
plugin ( <- but they are not masters of course ). I should add that i
load my driver with kextload and kextunload ( the driver-plugin path
starts like this '../../../Users/....' <- that seems to work because
Audio MIDI Setupt and others do load my plugin ), and that my device
is a usb device, even though i don't set the usb transport flag yet.
Someone Help?!?!
Greetings
Fabian Renn
