Missing audio channels with Raspberry Pi and 5.1 Audio

  • Hi

    When play movies with 5.1 audio, I only Hear the front left and right speakers

    tested with rpi3 and rpi4 , both same problem.

    Audio route: rpi->hdmi cable->samsung TV-> fibre-cable-> Onkyo Dolby-Digital Amplifier;

    Settings in Kodi to 5.1 , enabling "allow passthrough" gives no sound at all

    when playing from Bluray-player (also hdmi to tv and fiber from there to Alplifier) it works fine.

    Using LibreElec 9.1.501

    Somebody any idea how to solve this ?

  • Did you check "sync playback to display" (no passthrough)?
    Did you check different cables and hdmi ports on your Samsung and exactly the identical connection as your working Bluray?

  • I have the same configuration but with components from other brands...

    I have the audio settings like this and it works.

    Since the TV only supports dolby digital output, I have DTS disabled in Kodi and so when the sources are in DTS it sends the dolby digital signal in it.
