It's very simple: A player should always untouch a signal. It's up to the endpoint to handle the audio / video. Only if there are issues (old devices, no compatibility or quality issues) you should use workarounds like changing the signal (audio or video) on the devices which plays back the media. These are HiFi basics. Here again the use case:- I want to hear Dolby Digital, DTS, TrueHD, DTS HD Master, etc. Those signals should be sent as bitstream and untouched to the AVR--> This is always working, no matter which speaker configuration I set up in the Windows Speaker Config- I want to send PCM 2.0 as PCM 2.0 and PCM 5.1 as PCM 5.1 to the AVR. PCM 2.0 will be used by many TV channels in SD quality (MPEG2 Audio), or Internet Radio, MP3s, etc. PCM 5.1 will be used by some Blu-ray Discs, 5.1 FLAC, 5.1 in web video players (here is a 5.1 test: <a href="https://www2.iis.fraunhofer.de/AAC/multichannel.html" target="_blank">https://www2.iis.fraunhofer.de/AAC/multichannel.html</a>)--> This is not working. Because if I set up 5.1 in Windows Speaker Config, all PCM 2.0 signals are packed in PCM 5.1 signal (NOT upmixed!). If I set up 2.0 in Windows Speaker Setup all PCM 2.0 signals are correct, but than PCM 5.1 is downmixed to PCM 2.0.So there should be two options:1.) You are using an external active audio device like AVR, Soundbar, etc. In those cases ALL audio signals should be sent untouched to the device as they are2.) Your PC is the "AVR", because you are using your internal sound card with active speakers. Those user should be able to set up how many speakers they have (2.0, 2.1, 5.1, 7.1 etc.) and whether the signal should be upmixed or not.</blockquote>
