Is samsung 5 series led tv supports audio return channel (ARC)? I searched in samsung website, but I could n't find anything about this. And they did n't mention HDMI version too for UA32D5900 model tv. I have sony DAV DZ 340k home theatre along with ARC support. Here the problem is home theatre has HDMI audion in (ARC), coaxial audio in, but the TV has only optical digital audio out. Please anyone suggest how to connect SAMSUNG LED UA32D5900 audio out to sony home theatre (DAV DZ340). Thanks in advance.
