I just upgraded to vista and am awaiting the release of 7. After i installed vista my logitech sound system doesnt seem to be working. One speaker wont have anything come out of it at all, Another is overally loud and the other 3 are really quiet but still have sound barley coming out of them. The Base is also quiet as hell. I installed the drivers, Its a Realtek high definition audio intergrated soundcard on my gigabyte Mobo. When i go into the realtek audio manager and do the test i only get sound out of one speaker on the test. I did not have this problem with xp and have checked all the wires and they are good.
