[RPI5] Video and Audio on different HDMI ports not working

  • Hello
    My auto output via HDMI is not working with the Raspberry Pi5 if TV and AVR connected to separate HDMI connectors.

    Audio Not working:
    HDMI 0 -> TV (1080p 60Hz)
    HDMI 1 -> AVR (HDMI 1 selected in the Audio Settings)
    Video setting I tried: 30Hz, Blank other Displays

    Audio working fine if TV is connected to the AVR:
    HDMI 0 -> AVR -> TV (1080p 60Hz)

    I need to use the first setup because my AVR supports only HDMI 1.3 but the TV 2.0b (4K)

    Surprisingly if I use the same SD card in a RP4 it is working as expected. I have the same issues when I’m using the Raspberry Pi OS.

    Thanks you for any help
