i used to use 2.0 sound because i had a set of Pro-Logic II speaks that did some neat 5.1 built in.... they fried.... so i baught some logitechs that are 6.1 ... plugged them in... switched the mixer to 5.1.. worked awsum.... was true 5.1 for the longest time... then all of a sudden i needed to do a system restore.... lost the true 5.1.... i updated the drivers.. formatted the computer... installed windows XP .... updated those crappy drivers... i only get 2.1 ... the rest are VERY faint.... i get the 5.1 when using a DVD or an EAX game....but it wont give me 5.1 all around any more... any help would be greatly accepted.. i wanna listen to my MP3's again.. in 5.1
