Here is the problem I am having. Purchased new Sony XLR 77 TV with eARC and thought it would work with my old Denon X3400H AVR with ARC. It seems, I am told that the y are not compatible. Denon and Sony both say that they both should be eARC to eARC or ARC to ARC, eARC to eARC with all of the eARC (e is enhanced) enhancements of full DolbyTrueHD, etc. for the best quality sound of all the dolby stuff. and best picture you can get out of 4K or 8K, etc. If you HDMI from eARC TV to ARC AVR (as in my case) you do not get the e(enhancements)ARC (the best dolby, sound, pictures, etc) it is dumbed down a couple of levels. And has in my case it messes up lip sync, it will not give sound to TV from Cable, and other things, just a lot of set up problems. (did I just waste $3000 on a new tv because I did not know of the incapability of eARC TV to ARC AVR). H ow many people are making this mistake? A lot, look at Utube on this subject. I have had this New Sony eARC tv for 4 weeks and tried every setting I can find on the TV and my AVR. Nothing works. They told me to hook a Digital Optical cable from TV to AVR, it does not work. Even if it did work it still does not give me the optimum enhancements I was looking for with the new Sony XLR tv. Denon says the only way to achieve the full enhancement is with eARC tv to eARC avr. That would mean another (after research) $700.00 up to $xxx dollars by upgrading my Deonon to eARC level. I found a company that invented unit to interface between eARC TV and ARC AVR for about $500 so a lot of people already know about the eARC to ARC incapability problem and it seems not all people have the same setup issues depending on their equipment. So my question is does anyone know how to solve this problem without spending a lot of money to make eARC compatible with ARC? New TV buyers beware if you are trying to upgrade your sound system with a new tv. Help.
