My friend bought a 7.1 system this weekend and it has been a nightmare getting it all hooked up. The first problem was that the AVR only takes the video and passes the audio from the HDMI on through to the TV. So we decided to go with that and use the optical out of the TV (samsung) to pass the audio back to the receiver. No luck on getting any audio that way. So we ran the audio from the PC straight to the AVR via optical. WE get audio but we can't seem to get anything else other than 2.0. We set the audio setting in the control panel to 5.1, 7.1 and run the test but still nothing other than the left and right speakers play audio.
But when we play a movie via TMT set to 5.1 it seems to trigger the center channel to work.
The MB is an Asrock with Via audio and the website says that chipset wil do 7.1. Are there any tools we should look at to test what is getting sent to the AVR outside of hoping the AVR displays an icon?
