Changing Default Playback Device
The simplest and fastest way to change your playback device is to find the icon for sound in the notification area (lower right corner of your screen) and right-click it.
You'll see a menu that offers several choices:
Open Volume Mixer, Playback devices, Recording devices, Sounds and Volume Control options.
When you click on the Playback devices tab, a window will pop up that shows you the devices available on your system. Each system is different, so what you see will reflect that.
Your current default device will be indicated by a green check mark.
If your computer says that the HDMI Output is your default device, you need to right-click or tap on Speakers, and then choose Set Default. Click okay to close that window after setting speakers as the default.
If you do not see these option or are having issues changing the audio source, please submit a Help Desk Ticket.
