Hello!
I can't get PCM 5.1 passthrough to work correctly. When i select "Non decoded hd audio ..." in PDVD settings it outputs PCM 2.0 (pic.1). If i select "PCM decoded by PDVD" it outputs PCM 5.1 (pic 2). So PCM 5.1 output is possible, but only decoded by PDVD, not passthrough.
I have NVidia GeForce 720 with latest drivers. Earlier this spring i had same problem and i solved it by installing latest (at the moment) drivers 397.64. After that i was experimenting with Intel integrated graphics and when i return to nvidia PCM passthrough broke again. This time i can't get it fixed.

Whether it will output non-decoded HD audio to your HDMI receiver depends on how Windwos audio settings identifies your audio device's decoding compatibility even it is unlikely that your HDMI receiver does not support HD audio decoding.

While you are playing HD audio, did the supproted format of the HDMI audio device show properly that it has Dolby or DTS decoding compatibility at the exact moment?
Check your HDMI receiver's properties -> Supported format in Windows audio setting.

List of supported formats does not change either i play HD sound or not.
When PDVD plays PCM 2.0 i can change volume in the program. Is it normal for PCM passthrough?
