raspberry pi - problem with multi channel

  • Hi,
    I just migrated from openelec 7.0 to libreelec 8.0 on my raspberry pi 2.

    As I did with openelec, I configured libreelec with 5.0 channels, passthrough and disabled ac3/dts to get multi channel pcm on my denon AV receiver.
    While it worked perfectly on openelec, behaviour is very inconsistent on libreelec.

    Sometimes, I get the 5 channels on my 5 speakers but sometimes, I get only the front left and front right channels (no rear and center).
    tested with DTS/DTS HD MA and AC3.

    I can't find anything in the logs (logs from same video file)

    logs when working:
    multi channel working - Pastebin.com

    and not working:
    multi channel NOT working - Pastebin.com
