+About autodetect gamemode and desktop audio:
+
+For autodetect gamemode audio, enable it only if you're using HDMI audio from your TV, and TV is off in desktop mode.  
+BigPictureTV will look for new audio device connections, and since HDMI is off when screen is not used by windows, it will find it.
+
+Autodetect desktop audio will save your default audio output right before switching, and try to restore it when going back to desktop mode.  
+If your device is disconnected when going back to desktop mode, audio switch will fail.
