Hi all, I have a on board via hd sound processor witch has options for 2 4 6 and 8 channel audio, but I use only stereo and a sub witch i suppose is 2.1 but unless I select the 6 channel option in HD Audio Deck I can't use the sub properly and if its in 6 channel games sound crap because they process the audio in surround. Any alternative software or a means of having the sub option in HD Audio deck while in 2 channel mode?
