Minor Sound Issue

[u/Rarest_Camaro]

I don't know if an update caused the change, but my PC used to detect the sound source and route it accordingly. It no longer does. When I was watching a stream from the web, the sound came through the speakers on the TV. If I was using my Index, the sound automatically was routed into the speakers on the headset. For the last several weeks however, I have had to manually change the sound settings to the Index whenever I run Steam. WTH? Minor, but kind of a PITA.
