Hi, After I refurbished the room, I do not get any sound anymore from the center and rear speakers of my Bose Lifestyle 8 system. No matter which option I select with the remote, only the front speakers work fine. All cables are correctly connected. Also all speakers work separately (I did test this by connecting each speaker to one of the front outputs). I basicaly tested this with radio and DVD player, so no funny setup with video or whathever . Can one help? br Peter
