Thanks Robert for your reply. Then let me clear u fully.......
I have
1.sony smart android 3d tv, which has hdmi, hdmi arc, spdif, digital audio out port.
2. Set top box that has spdif digital, hdmi and rca port.
3. Siphon hdmi to hdmi converter that has spdif, hdmi out, rca L R, hdmi in arc.
4. 2.1 analogue soynd system
5. Hdmi, spdif, digital coaxial cable.
Now if I connect hdmi cable from my tv to siphon converter, then hdmi from siphon to set top box, and rca cable from siphon converter to analogue speaker, I get good sound quality from tv channel only. If I play youtube or internet movie from my tv I get no sound from sound system. I get only tv speaker sound which is normal sound not digital.
Now I want DTS sound from both my tv channel means set too box and tv youtube or interner movie from my tv.
How can I connect all these to get it.
I will be grateful if I get a solution....
