Samsung 43KU6470 : Need help regarding Optical audio



New Member

I just got my new Samsung 43KU6470 UHD Tv. And, i'm really impressed by its picture quality. I also received a Samsung 2.1 channel Speaker (HW-K20) under Samsung Utsav offer.

But, i have 2 concerns with the new tv:

1) New 2.1 channel set only has RCA/3.5mm input, while the tv has Digital/output only. So i'm planning to get a Digital-to-Analog adapter(costs about 800 bucks). But, i have read in forums that new Samsung TV's fixed audio output via Optical audio(So we cannot control the volume using TV remote, hence can only be controlled by speaker volume knob). Is it true? In that case how can control volume of any external speaker that doesn't have its own remote?

2) I have an Airtel DTH HD+ connection, but i cannot program the Airtel remote to control tv volume or any other function apart from switching on the tv. I presume that new samsung smart remote doesn't emit LED signal (apart from Power button). So has anyone been able to program their dth remote with new Samsun KU series UHD tv's ?
