Most learn to use Optical cables when ARC messes up like this. A few will demand justice or think ARC is all worked out.

Samsung series8 TV running through a Sony str-dn840 receiver. Had the ARC working fine when watching Netflix through Smarthub, then it just quit. TV seems to sending a signal as receiver will switch to TV and the ARC indicator is lit. If I pull the HDMI cord for a few seconds and re plug the sound will come on, which is workable but frustrating. Any ideas what causes this? Have checked all the settings and they seem to be where they should be
