When I first installed Oculus home to set up the Rift on my windows 10 machine it set Headphones Rift Audio as my default sound playback device on the control panel. This prevented any sound at all from coming out of the speakers I have on my desk. I found I could restore the use of my desktop speakers by setting "Speakers" as my default sound playback device and when running VR games audio comes only out of the Rift headphones as it should be but I have experienced a few problems with audio in various programs. Most significantly in Virtual Desktop all sound comes out of the speakers on my desk instantly and out of the Rift headphones four seconds later. Switching the default sound playback device to the Rift Headphones gets rid of the lag but, again, disables the speakers on my desk for all purposes both in and out of VR.
When you set up your rift how did it interact with your sound settings in windows 10? Was it selected as default? Did you have to change it? Has anyone else had any problems getting sound to come out of their regular speakers when they installed Oculus Home?
