hey all,Iwas wondering if anyone out there has had these problems,I have acouple of live5.1's all have serial#0220,one of them works fine with kx drivers,but the other two will not swap front and rear speakers,only the front output will work,and when using any type of v.a(amplitube,nomad factoryetc)I get horrible whistling noises and such when playing live,but only when the line input is used,when using the mic input for live playing the noise does'nt occur,but ofcourse the sound quality sucks when the shitty mic input,as far as I can remember the one sb0220 that works fine was purchased about a year and ahalf ago,but the other two sb0220 were bought a few months ago,Is creative trying to detere people from using any other drivers on they're cards?,or could this be inconsistent quality issues?,one thing is certainly strange,I installed the shitty creative drivers and the rear outputs worked fine on both cards!,what the hell's going on,this has me pissed cause its to late to return the cards where I got em-BAFFLED-FRUSTRATED-AND PARANOID-FLEER
