Bought the UN55F7100 in early May and really like it. Also bought Sony STR-DN840 AV Receiver last month and proceeded to hook things up. After using the combo for a few weeks now, I have some of the same issues discussed in this thread. My main problems are power on for receiver & tv, switching audio signal to TV on receiver (done erroneously by TV), and sound cutting out on receiver when watching content through Apps.
I read the user manuals and understand how things are supposed to work with ARC. Have Xfinity cable box and Samsung Blu Ray player connected to receiver, and receiver output to HDMI 2 (ARC) input on TV. Have HDMI settings set correctly for ARC use on both receiver & TV (I think),
Having the 7100 switch the audio on receiver back to TV (rather than Sat/CATV) is a pain. I can adjust, but it screws up everyone else in the house that aren't techies and just expect the things to work. Well, I expect them to work too.
If this was the only ARC problem I might figure out a way to deal with it for TV watching. But it isn't. The most frustrating thing is trying to watch content from one of the Apps like Netflix or Amazon Prime. In that case, the ARC correctly sets the receiver to "TV", and I get sound. However, it cuts out for about a half second every 30 seconds or so, and sometimes cuts out for a few seconds. On the receiver I see the Dolby sign, D.L.L. (Dig Linear Legato), and A.P.M. (Auto Phase Matching) flash when sound cuts out. On receiver I turned off (separately) APM & DLL to no avail. Didn't try turning off both.
This happens with any App. Sound is fine if I turn off receiver and listen through the TV (unacceptable in long run).
HDMI cable is high speed 1.4, and is 10 feet long.
I did not read all 38 pages of this thread, but searched the thread for my concerns, and here is what I learned:
ARC and Anynet+ are a joke, not ready for prime time and not implemented well on many manufacturer's equipment.
If I want things to work, I have to connect TV digital audio out to receiver audio in, turn off Anynet+, then customize my receiver settings in order to try and make it simple enough for all users.
Question: Am I possibly doing something wrong with settings on TV or receiver? I feel problem is on TV. Wiring the digital audio is a pain but I will do it soon. Hopefully that will solve the problem, even though I'd rather use all HDMI cables.
Tried quick-n-dirty optical audio option (not fed behind entertainment center). Turned off Anynet on TV. Using HDMI2 (ARC) the sound still cut out, even for regular TV, Connected receiver HDMI out to HDMI1 on TV, and audio does not cut out any more, even on Apps like Amazon Prime. Receiver does not have APM and DLL on anymore, though. Sound is good, but not sure if sound is as good. Maybe settings on receiver are set by source and maybe I'm losing something by not using ARC.
