    I cannot get true 5.1 audio with my Intel NUC DCCP847DYE

    waLIEN

      I am using XBMC (Frodo) with Windows 7 SP1 (x64). I have the settings in XBMC set to 5.1 via Optical. Sound output only comes in the front channels (stereo).

       

      When I go to the windows speaker configuration, it says it only has support for Stereo.

      I have it hooked up as follows:

      Intel NUC -----HDMICABLE-----> Samsung TV
            \______-----HDMICABLE--->HDMI Audio Extractor----Optical Cable---->Vizio Sound Bar

       

      When playing the Dolby Digital channel test, I can verify that audio only comes out of the stereo channels: http://download.dolby.com/Content_Download/ChannelCheck.m2ts

       

      As of today, I have the latest BIOS and all Intel Drivers. I'm at a loss as to why I can only use two channels. Any help would be appreciated.

          By the looks of your diagram, I don't see how your Vizio Sound Bar is able to return its capabilities back to the NUC via HDMI through your HDMI to SPDIF converter. Since its 5.1 capability is not reported to the NUC you will only see the default 2 channel stereo option for the HDMI audio device.

            Hi,

            I had a similar setup until recently.  As Louie says, the windows audio drivers have no way to read EDID information indicating the 5.1 audio capability.  But with XBMC - you can configure it to do pass through audio and the soundbar should be able to decode the audio properly as 5.1 audio.  See: Settings/System - XBMC

            - the 'Passthrough output device' part.

             

            I think the only way to get windows (with the drivers) to do 5.1 audio is through HDMI into a receiver or a TV that has support for it directly.  This is because the audio driver has to send the audio raw and uncompressed over HDMI for each of the channels (I believe in the case of the optical cable the audio must be already encoded as DTS or Dolby).
