The Denon may be looking for a sound signal from the TV's eARC port.
it will only look for ARC when audio is being sent and you switch the input to "tv audio" otherwise, it will seek audio from either the HDMI input selected or an assigned analog or other audio source that is assigned to that HDMI input. if that's the PS3 connected to the "game" input, you should be putting both video and audio into that port. you should get sound. but, he's saying no sound at all.
ARC would fall into play when devices are connected to the tv then audio is streamed from the tv to the receiver to hear those devices connected to the tv directly. he would still have to select "tv audio" to hear the ARC audio.
i do notice an optical cable connected, wonder what that's from and if the user gets audio from that.
also, OP, please make sure the receiver is turned off before doing any switching of anything. Lord don't unplug or plug in any speakers while it's powered up. that is a for sure fuse blowing/damaging thing for the receiver. i mention that because in one of the post the OP mentions he heard a hum when plugging in the second speaker or something like that.
it sounds like it's a receiver issue as you should almost always get sound from at least the front L&R speakers.
