Hello,
I'm trying to test the example code for the AudioDriverKit and the "Open User Client" button returns a kIOReturnNotPermitted error. Using the standard entitlements that come with the example and I'm signing to run locally. SIP is disabled and I'm using
systemextensionsctl developer on
When the "Open User Client" button is pressed, I see the following calls into the dext:
SimpleAudioDriverUserClient::init
SimpleAudioDriverUserClient::Start
SimpleAudioDriverUserClient::Stop
SimpleAudioDriverUserClient::free
None return any errors.
Seems like this is a permission issue, but since this is just the straight example code, it seems like it should work out-of-the-box. Any clues as to why this is failing?
Thank you!
