You are running VIA high definition audio... sometimes Windows 7 doesn't always have the complete software to drive the drivers
to its full potential.
have you tried to go to VIA's website to see if there is particular software pertaining to these particular drivers.
I have Realtek High Definition device on my mother board and to get the complete software and drivers for this sound card.. the file is as big as 50 meg. Within that software that came from the website, i can make my sound card do whatever I want..
You probably just have the basic drivers that came with Seven or when Seven downloaded from Windows Update.
Update: I was just looking at the photos...
You have HDMI going to your computer screen which should be picking up the sound.
If you are going to drive sound to an external Amplifier; you need to turn on the other drivers which you have disabled.
If you will be using 5.1 channel, not sure if your sound card has Fiber out.
I am looking at the manual for your reciever.
It looks to me that there is 4 HDMI ports on the back:
HDMI (out to TV); HDMI 1; HDMI 2; HDMI 3
Could you plug the HDMI cable from your computer to HDMI 1 and from HDMI (tv) plug another cable into your Monitor http://www.1800customersupport.com/p...RT2906_RCA.pdf
