Once a cable was working though, I had no ARC issues. However since taking the .60 OTA I have had the issue mentioned above a few times, where ARC forgets it is active, for example volume doesn't work and no sound...so have to turn off TV. Once I turn back on, works. It has happened maybe 3 times since I took .60

ARC is a subset of HDMI CEC.
HDMI CEC is an optional and unregulated part of the HDMI specification.
All the manufacturers involved in creating HDMI voted for it to be this way because they wanted to use their own CEC command sets in order to attempt brand lock in.
Manufacturers are free to use their own version of CEC and many do, LG use simplink, panasonic use vieralink, sony use bravialink and so on.
None of them a guaranteed to be interoperable and problems such as this are rife.
As long as its unregulated like this, these problems will not go away and the ONLY surefire solution is to not use ARC , use an optical cable instead.
