Audio channels wrong.

  • Hi,


    I have a RPI4 with the latest version of Libreelec.

    When I start some movies the sound channels are wrong. No centre, hard front right, no rear right.
    I did already activate the sync to refresh rate. When I did enable this option the first time the audio was fine.

    The next day. The audio was with wrong channels again.


    If I stop and start the movie the sound is fine sometimes. I must stop and start the movie 3 or 4 times. When the audio channel is right the whole movie plays fine.


    Where could be the fault?

    Setup

    RPI4 > denon avr-x4400h > Philips old tv without acr.

    All HDMI cables of course.

  • Let's start with some basics, and perhaps bypass the AVR for now so we can establish a base line.


    Please provide a full debug log.

  • That's an unusual error, so my bet is an AVR issue. After many years the audio channel relays might get weak.

  • Channel swaps with multi-channel PCM output is a well known issue on RPi4. It'll be fixed in 9.2.4.


    so long,
