Raspberry 4 : no audio from HDMI 1

    Hello,

    I have libreelec on my rpi4, and there's no audio output on the HDMI port 1.

    The HDMI 0 is working properly, but I can not use it because it is too close to the USB-C port. I added

    Code
    hdmi_preferred=1

    to the config file but it is still not working. This is making me crazy.

    Thanks.
