just hooked up new samsung tv with toslink cable to my 5.2 stero reciever. the problem i have is now i cant get the reciever to play the same audio as zone 1 on zone 2. ive tried everything and im at a lost. With the RCA cables i had before i had no problem but when i switched to optical cable i cant. should i be looking for a buttom on the reciever to do it
