Channels mixed up.
« on: July 10, 2016, 12:06:31 PM »
Hello
Could someone help me please?

I'm trying to get 5.1 sound on my home cinema from PC through SPDIF form my sound card, to do so I use Virtual cable to send sound to AC3filter so i can encode it and send it to my Xonar U7.
It works i get better sound with better bass and all channels work BUT then i downloaded few surrond tests ( http://www.demo-world.eu/dolby-dts-thx-wmv-distributor-trailers-sd/ [nonactive] ) and I have noticed some issues:

When center plays, left and right plays too.
When left surround (back) plays, left plays loud too and surround only quietly.
When right surround (back) plays, right plays loud too and surround only quietly.
And the subwoofer doesn't play at all (only in the tests).

I'm not sure where the problem is, I tried a few things like tunning the mixing matrix or trying the amplification, didn't help at all (maybe I have done it wrong?)

Setup:
Home cinema: Samsung HT-C5550 + wireless transmitter for surround speakers.
Sound card: Asus Xonar U7 (external via USB)
Virtual Cable 4.13
AC3 filter 2.6.0b
GrapStudio 0.3.2.0b
Windows 8.1 64bit

I'm attaching some screenshots of my settings. (On GDrive)
