P67 Sabertooth no 5.1

Can anyone help me? I have no option for 5.1 or 7.1 optical audio under the advanced settings in properties. I only have 2 channel options. My old gigabyte ud4 was the same until I updated the bios. The properties then had the dolby upmixing section with dolby prologic II. I only want 5.1 for watching movies. Do I have to wait for a bios update?

  1. My assumption this is a set-up problem and not a BIOS problem, and I assume everything is up to date and installed properly.

    In the BIOS:
    The following needs to match up with your source out.
    HD Audio Controller [Enabled]
    Ft Panel Type [HD] ; AC97
    SPDIF Output [SPDIF]

    See Manul page 4-4; the access is in the Task bar 'Realtek HD Audio Manager'

    Verify the outputs and set-up:
    ]

    Verify the outputs:
  2. I have the bios set up that way but I do not use any front panel (front spdif) so it is disabled. Realtek digital output(optical) still does not have any options other than 2 channels
  3. What physical output connections are you using? What's the PC connected to? Remember WMA files will not playback on the S/PDIF.

    From above Sound/Playback is from my ASUS P6X58D-E. So if I were to connect to my rear S/PDIF I would first connect the disconnect any Analog outputs, connect output to the optical @ rear I/O, and use the Digital Output (Optical) tab {press the Set Default Device} from the Realtek HD Audio Manager. Verify Sound/Playback = Digital Output (Optical).

    In my case I have Coaxial / Optical S/PDIF out ports {Digital}.
  4. I only use the optical for movies everything else is megalodons for games and music.
    I don't use spdif for anything.

    Optical works but only 2 channels when connected to my receiver.
  5. I just tried my ASUS and updated the image above. You need to also click the DVD Format button. Both my PC and Receiver both use 24-bit, the DVD {Menu} was set to Dolby 5.1 {tried Star Wars}, and my Player supports Dolby.

    So any of those might cause a problem. Also try disconnecting the 'other' analog outputs.
  6. hmm i will have to try these
  7. o brother i also face the same problem.still didnt got any solutions!!
    i think i have to download some "codec" or some thing to provide a 5.1 spdif optical output.something called dts connect or dts interactive.
    i didnt tried that.help me too
  8. zoom player works if you enable spdif

    You aren't going to get 5.1 dolby digital live or DTS connect coming out of the motherboard's coax or optical port. You need a sound card for that.

    Re: jaquith's pics - are you saying that you need to press the DVD button to enable a 2 channel digital out to carry a 5.1 encoded stream to output to a receiver that will decode it in 5.1? Previously I have always left the digital at 2.0 channels in the setup and when I play a dvd or bluray it sends the stream and voila! 5.1 emerges from the receiver. Not sure why you would need to press DVD. Some DVDs are only in 2.0...
