(Please understand my bad english, I'm from Korea so I cannot speak English well)
In the past, when I turned off the headset it would disappear directly from the audio devices section on Windows and the switching between audio devices was automatic. Now when I turn my headset to the usb position, Corsair Virtuoso auido device is still active in the audio devices on windows and I have to go to the windows system tray and manually change the audio output. This is very bad.
