Hi!
Good news!
I already had done everything you told me, everything I read in the user and technical manuals, in the forums, and ... still no audio when the input source is one of the HDMI inputs!
Today I decided to do a last test with the Marantz 7011 before I pack it to send it to repair. So, very early in the morning, after another restart (one more) as you and the manuals say, no audio from HDMI sources yet! I decided to go through all the AVR menu and turn off everything in the menu that I didn't need and ... at last, something I hadn’t tried before to repair it, to reconfigure the Audissey again (using the included microphone) and ... it started to send audio to the speakers from the HDMI inputs as source, again!!!
After that I did a lot of tests, tried all the HDMI inputs and tried the ARC from the TV (LG65E6V) and, as much as I can say, its working with all of them including the TV audio by ARC (I tested it with Netflix playing in the TV)!
Conclusion:
Problem: For some reason that I don’t know, the AVR stopped sending audio to the speakers when the input source was any one of the HDMI inputs, including ARC from the TV. The last different thing that I remember related with the Marantz 7011 was to notice, at night around two weeks ago, that it was doing a software update. At the time I was using the AVR only in the mode pass-through (powered off) so I didn’t notice nothing different at the time. Only a few days after I noticed that there was no audio from the speakers when the selected source was one of the HDMI inputs. The video image was good!
Solution: The usual restarts as the manual says, redo the installation of the AVR, including the Audissey part of it (it only worked after the new Audissey reinstallation)! The strange thing is that, even with the factory restarts and all, the AVR didn´t start to let the audio go from an HDMI input to an HDMI output or the speakers, only after I mess with the Audissey configuration again!
Thank you for your support!
