Hello. I was trying to make a game to recognize my 5.1 speakers, but no luck. I created a ticket, but a month passed without any answer. So I'm switching to mono, 4.1, 7.1- none of them are working. Any option gives me stereo, even Dolby, Mono and so on. I got SB Z soundcard, using Windows 7 SP1 and my speakers are Logitech X-540. Can anyone please confirm if 5.1 is not giving you stereo? Or if Mono or 5.1 is actually working as intended? Thanks.
