CSGO default sound device not changing

Found a bug, where if your sound device is set to the default device, and you change the default device whilst in-game, such as from speakers to a headset, not 2 separate sound devices, not plugging a new device into the jack the old one was plugged in, the sound in cs does not play from the new default device until the audio options are opened and you click on the audio device option. Found problem switching between usb and analog sound devices, headset and speakers.
