PCM multichannel audio bug
On the current firmware 3.13 of 4K SE HDR player there is a bug with the output of 5.1/7.1 multi channel PCM audio track to the external AV reciever. With every settings (RAW, multichannel, Auto) the player outputs only 2.0 stereo sound. Please fix this bug.
You must set both HDMI audio output to RAW
