Windows 7: No Multichannel Sound via HDMI

25 Apr 2012   #1

Windows 7 Ultimate x64
No Multichannel Sound via HDMI


I need help with the following please:

I have connected a HTPC (Zotac Zbox AD05, AMD RADEON 6320) via HDMI with my AVR (Denon 3808). Unfortunately I do not recieve any kind of multichannel sound.

As long as the windows settings are on stereo I recieve DD2.0, once I change the settings to multichannel (5.1 or 7.1) I only recieve "normal" stereo.

I have tried the following players: VLC, XBMC, WinMediaPlayer
I have tried it with video (DD5.1 and DTS) and audio (DTS and DTS-HD) files. Always the same result.

ATI Catalys (as of today I am not sure about the version)
Realtek High Definition Audio R 2.68 for Win 7 x64

Any ideas?
