No movie audio and rare IPTV audio

  • Hi,
    Just getting started with LibreElec and hit a stumbling block.
    Music plays fine, but I get no audio from movies or most of my IPTV channels.

    I assume it's a codec issue, but don't know exactly what I'm lacking (possibly aac?) or how to add it.

    Log file attached, booting, trying to play a movie then quitting.

    Any advice would be very welcome!
