Audio Device events not working

Hi,

I wanted to detect
when the audio output device is changed in the device settings and so
subscribed to the OVRManager.AudioOutChanged event, but it seems like
the event never gets invoked.

I’ve tried getting
the event to invoke, by switching the Rift’s Audio Ouput in VR setting between both Rift Headphones and Use Windows
Settings options, which according to this post should invoke the event. I’ve also tried changing the default
windows audio device, but none of these actions caused the event to
invoke.

I’m using Unity
version 2017.3.1f1, with the latest version of Oculus Utilities
(1.25.2), on Windows 10. I've gone through the list of known issues with this version of the Oculus Utilities, but didn't see anything related to this issue.

Thanks for the help.
