CRAP, that's not what I wanted to hear. I've been searching for an "official RX-V### owners" thread containing last year's RX-V371 base model, but couldn't find one, so I'll put this here for now.
I just discovered how to enable ARC and that my TV supports it. When it works, it works fine. Only problem is, quite often when I switch TV inputs from PC back to TV, the sound will cut out. I don't mean it's there then I lose it, I mean out of the blue when switching back to TV, there's no sound at all. I can re-enable it by going into HDMI>ARC and setting it to Off, then back to On, but it's annoying as hell.
The only other thing I can think of that may pertain to it is when HDMI>Control is turned to Off (which keeps ARC from working even when ARC is on), there's another HDMI option shown, Audio. The HDMI>Audio mode can be set to Amp or Amp+TV. It was having these problems in Amp+TV, so I switched it to just Amp, then Control back On, since I have my TV speakers disabled (I assume that's what they mean).
I have not tested it enough in HDMI>Audio>Amp mode to know if it will fix the problem, nor have I checked recently for firmware updates on my TV, but last I checked, including just recently for the receiver, there was none. Conversely the tech I just spoke to at Yam yesterday said the RX-A710 has an update available that fixes some minor bugs. Don't know if the 720 does.
I don't want to have to go back to using an optical audio cable like I was previously. Never had any problems with it, but the sound quality isn't quite as good and every time I changed the TV to TV input I had to also hit TV on the receiver remote, whereas ARC does both with the input switch.
If I keep having the problem I'm going to talk to an upper tier tech at Yam and see if they can enlighten me to something I may be missing. If so I'll report back here. I may be kidding myself though, because I have a feeling when HDMI>Control is On, it automatically sets up HDMI>Audio to a set parameter that can't be changed.
