If not, then you may just have a bad unit that needs to be replaced (most likely scenario).
I got a replacement 80 unit and set it up today.
First had a extremely difficult time getting it to connect to my network.
Had to manually enter all the info, as the auto configuration would not work at all.
Was finally able to connect, and successfully updated my firmware to the latest version.
Configured all the audio and video settings and put in my first test blu-ray movie, "Hellboy 2".
The movie play backed full 7.1 DTS-HD MSTR audio with an extremely aggressive soundtrack.
I was feeling pretty jazzed until I turned the unit off and powered it back on again.
Same frackin problem!!
The back surrounds were outputting stereo again, and I was not getting any test tones from my back surrounds using the speaker setup menu.
I was really feeling like throwing in the towel at this point.
I spent I don't know how much time on the phone to Panasonic support, as they said they turned the problem over to there engineers.
This didn't give me much hope as most of the time this gets canned, unless there are multiple cases of the same problem.
I decided to give it one last try, and completely reset the player.
(press power+pause+open, all at the same time on the front panel)
Reset the audio and video, but this time did some changes and removed some features.
Network cable disconnected, memory card removed and quick start disabled.
Previous setting remained the same: HDMI audio off, DTS-HD MSTR & Dolby True-HD output set to PCM, secondary audio off, 7.1 audio selected.
Played "Hellboy 2" again, powered the player off and tried it again.
This time it worked!!!
Have played "The Spirit", "Celine Dion", & "Spiderman 3", blu-rays successfully without having to reset the 7.1 audio again.
Right now I don't know which of these changes solved the problem, as it would require a process of elimination.
Since I like to tweak settings, I will eventually try to figure it out.
For now, I am HAPPY the audio is outputting correctly.
For people sitting on the fence between the Panasonic 80 and the Sony 550, the audio on the Panasonic, using the 7.1 analog connection, produces a MUCH MORE DYNAMIC POWERFUL SOUND field than the Sony 550 at the same settings and volume.
Picture on the Panasonic IMO, has slightly more pop than the Sony, but may not be a concernable difference to most people.
BOTTOM LINE : Overall best performance in picture and audio quality, having tested both of these units side by side, goes to the PANASONIC 80.
