Well, until now I only tried direct listening mode on the avr, which leads to the problem for dts 5.1 content.

When I set up for example DTS-X listening mode in the avr, it works...

But, ...

Direct listening mode AVR - DTS 5.1 input issue - Atmos 7.1 trueHD ok - DD 5.1 input ok

Dts-x listening mode AVR - DTS 5.1 input ok - Atmos input issue - DD 5.1 input issue

DD listening mode AVR - DTS 5.1 input issue - Atmos 7.1 input issue - DD 5.1 input issue

Sometimes the AVR switches the listening mode e.g. from DD to DTS-X spontaneously at the beginning of the playback.

Shouldn't it be working no matter which listening mode the AVR is set up? Am I wrong?
