I use Akai EIE audio interface with ASIO drivers. EIE has 2 stereo outputs, but I regularly use only one of them (I only use the other one when I connect hardware DJ mixers). However, the Windows speaker setup window seems to think that I have quadrophonic speaker setup, which is the only option. In all 3d games, for example, sounds that are supposed to be behind player character completely disappear from the mix.
How can I force Windows to use only the first output as stereo?
