Atmos Tru-HD outputs as stereo (sometimes)

    Hi, all.

    Bit of a curly one here. I'm having an issue with Atmos tracks occasionally playing in stereo, instead of the core True-HD.

    I can't be sure if it's an AV receiver issue, or LibreElec.

    My receiver is an old-ish Onkyo TX-SR608. It's True-HD capable & has never had an issue with normal True-HD tracks. However, occasionally when fed an Atmos track from my NUC5i3, it outputs in stereo (even though the front panel display lights up the True-HD logo). Strangely though, it's not all Atmos tracks & stranger still, if I come back to the troublesome file at a later stage, it'll play fine & the Onkyo detects the core True-HD track!?

    I suspect the Onkyo is the culprit, but I'm hoping someone else may have had a similar issue & found a solution.

    Any advice would be appreciated.

    Hi. Can You tell me what settings You use. I can't get my Onkyo RZ810 to play ThrueHD or Atmos. No sound. Even if there is some sound - no logo Atmos. Only PCM. My be i get something wrong in settings.
