Since the new patch the game does not care when I swap Output Device in the options menu.
Swapping Audio Device has been an annoyance for years with WoW, as the game audio doesn’t change when I change device in Windows, but this used to be possible to get around by simply swapping to any other device and then back to System Default. With this new patch that’s no longer possible since swapping the device doesn’t change the output while the game is running.
I often swap back and forth because when I’m on voice calls I want the audio in my headset, but when I’m not I prefer to take my headset off. I really don’t wanna have to restart the game each time for this to work.
