HDMI ARC no longer works on HTS5120/12
I connected my Samsung UE32D6500 to my soundbar HTS5120/12. Anynet worked like a charm for 5 months until today when it occurred the following problems:
In setup menu HDMI ARC is greyed out even after rescanning connections and it is not available with the source button on remote control;
Tv recognizes the soundbar but when trying to connect via the tv, tv says "Anynet device not connected";
Soundbar tries to connect to tv when this latter is turned on, but connection fails and soundbar returns to original audio source instead of displaying "Hdmi Arc" on soundbar screen; however, volume controls appear to work and it is possible to control the soundbar via the tv remote control and vice versa.
I have tried the following solutions:
Updating firmware on both devices;
Unplugging both devices for a long time;
Disabling and re-enabling Anynet on the Tv.
Before Anynet stopped working, I did not to anything, no power cuts, no configurations of any sort, just using the dvices normally.
