Have had these for about 6 months and had to unhook them to paint office. When I put them back my front right speaker sound is coming from the right rear speaker.

Have tested using the Creative Audio Center. "front right" and "rear right" both emanate from same speaker. Yes, all wires are in correct slots and this occurs in any stereo or 6-channel setting.

Had these mounted high before painting so can only assume they worked before. Either way not working now. Would like all speakers to get sound. ANy suggestions?

Check all your connections again. Still if you swear you have it hooked up correctly, try plugging something in incorrectly to see if you get a different result. In the midst of doing this you may find out what is actually wrong.
