My problem is a simple one: My brand-spanking new Onkyo 608 receiver keeps switching/changing listening modes, from Dolby, to PLIIx Movie THX Cinema, to whatever and it makes this annoying, loud, clicking sound when it does it. It happens simply by the passage of time, no channel changing, volume changing or anything else required. Besides call for help, which Iâm doing tomorrow anyways, is there something that I need to look for? I’d like to have a decent understanding before talking to any tech support. Please help
