    I tried both output devices. Both same outcome.

    You seem to have set the number of channels to 5.1 so you'll get PCM output - set them to 2 and make sure passthrough is enabled properly in audio settings.

    Just checked here, DTS and Dolby passthrough works fine here with 20220115 nightly.

    BTW: it also looks like you are using the wrong HDMI port on the RPi4 - use HDMI0, not HDMI1.

    i thought the channels was not applicable if you using bitstream.

    thanks will change port too

    You are correct, the "Number of channels setting" has no impact on bitstreaming.

    It tells the number of PCM channels to use when bitstreaming is not supported / not in use. If you have an AVR then you should set "Number of channels" to 7.1 so that a non-bitstream format (eg FLAC 7.1) is sent to the receiver as multi-channel PCM
