I upgraded from xp sp2 to vista home premium. My speakers worked fine before this, they are plugged in properly, have reverified this. Have configured sound to make sure all settings are correct. Says the speakers work fine and their are no problems. The sound is up to a significant level where i would hear it and it is not on mute. I do have the most current drivers also. Read some other forums on this but nothing solved my problem. Everyones response was to make sure the volume was up and the speakers were configured correctly. Mine are both of these so neither needs to be covered. Would really, really appriciate help fixing this. I like vista and don't want to go back to xp unless I cant get this fixed.
