I have a pretty basic system, Visio 47" LCD, Onky TX-SR707 receiver configured for 5.1 with Energy speakers & sub, two audio ins, including a Motororola dual tuner DVR DCH6416 and a Panasonic DMP-BDT220 Blu-Ray player. Connections are similarly mainstream, with Wi-Fi to the blu-ray, HDMI from the blu-ray and dvr to the receiver, and HDMI to the TV. Speakers are run with standard 2-wire, 14 or 16 guage.
This setup has worked fine since I bought the receiver, until maybe 6 weeks ago. Notable change then...the new blu-ray player and wifi connection. The problem first started manifesting itself as a crystal clear picture to the TV, but with no audio from anything plugged into the receiver, including the cable box, blu-ray, or even an ipod run thru the front auxialliary jack. Messing with audio modes fixed that the first time, a factory reset (dvd + power) fixed it the second time, and the third time nothing worked so I just took it out of the system and routed blu-ray and dvr straight to the TV. Here comes the funny part...a couple weeks later the same problem happened again, but this time it's no audio to/thru the TV. It doesn't matter if I'm on the cable box or the blu-ray player, there's just no sound. So last night it happened again, except this time my messing with it eventually got me some distorted sound, as in watching a football game and the announcers would come thru in waves, very scratching and softSOFTLOUDSOftsoftloUDSOft etc...distintictly unintelligible. I pulled everything apart, did a visual inspection of the HDMI cables for signs of wear/tear/rodents/cat/etc, found nothing wrong, so hooked back up thru the receiver. I tried to do an Audyssey set-up, but could get no sound thru the speakers for the microphone to "hear", so there was an unending "wait" mode. I gave up on that, factory rebooted, and suddenly all my speakers showed up as functional and I had crystal clear audio. Tonight, it's back to nothing anywhere from anything.
So if it were the receiver, the problem shouldn't have happened on the TV after I took the receiver out of the equation.
If it were the cable box, it shouldn't affect sound from the blu-ray, auxiallary jack, or tuner.
If it were the TV, well, that just doesn't make sense.
The blu-ray? How could that have an effect on all the other components?
The wires/cables look good. I'm at a complete and utter loss.
