Hi,
I have developed a virtual audio driver which gets audio samples and send them through the network. It works has I expect to.
I would like to get an exclusive access to the sound card while my application runs.
I don't know if I should do something in my kernel driver to lock the device, nor if it's possible to lock it from the driver (referring to the Apple documentation, it seems that the audio family does not expose any interface to access the device from user space).
It seems possible to lock a device using the Hog Mode but I can't find any documentation about it.
Does anyone have an idea where to find some documentation about Hog Mode and and how to implement the exclusive access mechanism ?
Thanks in advance for your answers / help.
Best regards.
