Im using a Gigabyte z77x-ud3h motherboard with onboard audio Realtek ALC898. I've read manual and troubleshooted I cant seem to figure out how to ge tit working with my 7.1 surround sound I have in my basement.
Im using the digital audio cable connecting to my amplifier. Normally on my consoles I had sound from my rear speakers so somethings not right.
In the settings for sound there is a few options.
HDMI sound (HDMI to TV) which I could use as I have audio out connecting to my amplifier.
Digital Audio ports
"Speakers" I think its the audio software onboard, its VIA Envy.
Under the speakers option I can test 4, 5.1, 7.1 and enable it however I don't have any devices that use more than sterio for the 3.5mm headphone jack. Unless I can get 7.1 sound on a headphone connector to my amplifer, my only option is configuring it for Digital Audio and HDMI audio. But under any options for those I cant configure for anything over Sterio. My only options are Sterio --(followed by varying kHZ and bit rate)
In my manual it says you have to use the side speaker¢er etc. in the 3.5mm jack area to get 7.1 sound. ??? I don't understand Cant i use the digital audio port ...
You siad I would need a soundcard to convert it into Dolby but under SOUND in my control panel I found the SPDIF option and under properties there is a page called Supported Format. In this page there is two boxes, with 3 option each
looks like this
Windows WMA Pro Audio
There are check boxes infront of each option and you can test and see which ones work. For SPDIF testing only Dolby Digital works so I only have that checked. Im assuming this is compressing the Audio and my amplifer linked above has features listed that say they can decompress Dolby and DTS. So whats wrong? 5.1 works fine when I test it in the control panel however games and even VLC player set to 5.1 does not use my other speakers.
