"Hear non-VR apps in VR" options for both in and out of Dash
Currently there is a new option to enable sounds coming from Windows to output through the Rift headphones, but it only works when Dash is active. Why not have an additional option for mirroring regardless of when Dash is being used? Say you want to hear notifications, music, videos, etc in VR no matter what you're doing. Without such an option, one has to manually go and change their audio device in Windows every time.
Workaround. Disable all other audio devices under windows settings, sound control panel. Set audio quality to 44.1kHz to avoid stuttering.

You can make rift audio your default audio player, that will send all audio through your rift.
You can even do this from VR with the new desktop implementation just right click on your speaker system tray.
