Solved, read "Edit" below.
Hello.
I tried this one on Realtek on board ASUS Crosshair VI Hero:
Installation was fine. I had to manually change the driver used in windows device manager though.
Iam using Spdif Optical cable and using 5.1, But if I choose Dolby Digital Live 5.1 in windows sounds:
I only get this error and it jumps back to 2 channel:
Same in the HD Audio Manager in Control Panel.
I tried also checking all the options in "Supported formats", didnt help.
When trying the test notes in "Supported formats", it seems to work ok for DTS and Dolby Digital and I can hear it and so does my receiver show up as 5.1
I also tried reinstalling the driver. No change.
Any ideas?
By the way, Until now, I was using a patch to get original realtek drivers to show up the 5.1 option in windows sounds. Without the patch on original realtek drivers there was never such option and 5.1 or DTS would only play if a Video player would set it for example. But many things depend on the windows setting to actually decide to use it.
EDIT:
Oh lol.
For some reason, after I installed it, the "Disable all sound effects" was checked and remained checked even after doing a completely clean realtek driver cleanup and reinstall the modded one.
After I unchecked it, I can use the 5.1 now. Had no idea this would disable 5.1
So it seems I got it working.
Still wish there was also the DTS option, but I can live without it
EDIT2: However after the clean install, I dont have that HD Audio Manager in control panel anymore.
And also, "Sound Blaster connect 2" still only has "Stereo" speakers configuration in settings.
So I guess I cant really use any of the effects things.
