You don't say explicitly, but from your response it seems your 5.1 configuration has "rear" speakers. My 5.1 configuration has "side" speakers.
This may turn out to be a difference between Asus and Gigabyte motherboards.
dale, I can see in your other thread, in the screenshots you posted, that you changed the connection from black (rears) to gray (sides) from one screenshot to another, so it wasn't because of the devices and drivers. The Realtek drivers will detect where you have connected your speakers and enable the outputs accordingly, that's why when you had the rears connected the sides were disabled and vice versa.
The correct setting, as the Dolby page linked there and any receiver will confirm, is that 5.1 surrounds are located about the same angle as the 7.1 sides. 7.1 adds rears.
The problem is that when a player outputs 5.1 channels and the Windows mixer is set to 7.1, Windows somehow sends the surrounds to the back-surrounds, not the sides. If the player sends 7.1, then all channels are mapped correctly, so it's not just a matter of sides/rears being swapped. (To add to the confusion, some devices/drivers like Nvidia's do
swap channels, but I don't think you need to worry about that scenario.)
The first thing you need to do is connect your speakers accordingly. Connect the 5.1 surrounds to the sides, and make sure the Windows settings are to 5.1. Do the Windows speaker test, not just the one in the Realtek control panel and check it's OK.
