Struggling With Audio Passthrough

  • Hi

    I am running Libreelec 9.2.3 on a PI 3 with a pfidac digi (optical) board (hifiberry clone).

    I have made the changes to config.txt and in the audio settings for kodi, I can select the hifiberry device as the audio device.

    Further down I can enable pass through, but the passthrough audio device is greyed out and still says HDMI.

    I believe I need to change this this pass through device (to hifiberry digi) in order to get a DTS/dolby digital signal passed through to my amp.

    Any help would be appreciated.

    Thanks.
