Is the firmware completely up to date on the television?
If so, please try factory resetting the television, and let me know if the symptoms persist.

New Samsung JU7500 TV and Sony HT-XT1 soundbar both connected via ARC using 1.4 compliant cable. Working on initial setup but turn TV off and back on again and no sound from soundbar. Tried optical connection with similar result. Indications are that sound is being sent from TV but not emitted from soundbar. Have gone thru soundbar setting but maybe missed something. What I can't understand is that it works on initial connect but won't after TV turned off. Would appreciate any help.
