Here is my Setup:
CPU: AMD Athlon 5350 APU
Motherboard: MSI AM1I AM1 2 x SATA 6Gb/s USB 3.0 HDMI Mini ITX AMD
RAM: 1x 8GB
OS: Windows 8.1

TV: Panasonic TH-PZ700u
Receiver: Yamaha RX-V573 7.1-Channel

(Connected VIA HDMI Motherboard to Receiver)

I am not certain whether or not I am receiving 7.1 audio through my setup. The motherboard and receiver are both 7.1 capable. However when I point my mouse over the volume icon on my task-bar, it shows my Panasonic TV instead of my receiver. When I right click the volume icon and select playback device the only available selection is my TV. I select Configure and test my setup, I get sound from all speakers.

I remember when I set up my PC the volume icon on my taskbar displayed by receiver, but now it displays my TV as the audio device. My question is how do I set my Receiver to be the main audio device if it is not so already?
