Wrote a mail to realtek:
Dear support Team,
see my problem:
Normal 5.1: Front / Center / Surround
Normal 7.1: Front / Center / Surround / Backsurround
7.1 HDMI of my Ati 4850:
5.1: Front / Center/ Back Surround
7.1: Front / Center / Backsurround / Surround
In the Realtek config Panel itself every speaker gets the right signal, (compared the sound to the lightend speaker in the configdisplay), but in 5.1 mode, the wrong surround speakers are activated!!!
Thats wrong, if I change between PCM Stream 5.1 to DTS/AC3 Passthrough:
Multichannel-PCM: Backsurrounds play as Surrounds:
AC3/DTS: Surrounds play as Surrounds
Can you help me?! That's not right, you changed the speakers in your driver!!!Back surrounds are only for center Support between und behind the main Surrounds Speakers (of the 5.1 configuration)not for player the surround sound in 5.1 movies!!!
Thanks a lot, greetings, Michael Weber, Germany
Onkyo 805 7.1 configuration
But sound is....wow...
I use PowerDVD, I can change between HDMI out and my other Realtek devices (all are working), while HDMI out I can change bitwenn AC3/DTS Streaming and MultichannelPCM
