I was hoping someone could help with this. Yesterday I bought a Denon AVR-3312 AV receiver. I thought it was all setup fine. But today it seems the sound on the AVR was not working. Volume up and down not working and mute had no effect. I then noticed the sound was coming from the TV not the speakers connected to the AVR. I have spent an hour trying to figure out the setting to get the AVR to control the sound and output it via the speakers. I am lost. I do not want the TV to come via the speakers, I still want that via the TV. I want all the devices I have connected to my AV receiver to come from the speaker; So thats my Oppo Blu-Ray, the PS3 etc. I am seriously lost. I know it willl be a simple setting. Can someone offer some help. The speakers are definitely working as when I go to internet radio I am getting sound from the speakers.
