I want to connect 5.1 audio to sony gn88d from my pc.But sony gn88d does not have 5.1 channel aux input.On its main board,There is an FPC connector named FR,FL,SL,SR,C,SW etc.

I connected phone audio there.Audio is not clear and broken audio. In schematics PCM1609KPTR (Digital to analog converter ic)> circuit ( filter or something)>M61530FP-D60G(surround volume control).



When I connect mobile output audio to the circuit(filter ?) before the surround volume controller ic, now the audio is clear. but 90% volume is decrease.

Any solution?

Or

Is it possible to convert the phone audio signal with the same characteristics coming from the PCM1609 ic?


Sorry my English is bad.

 

What is not stated is what format the 5.1 audios in. Is it digital or analog? Is it five analog lines?? What is producing that signal from the computer???
Also, I am not familiar with a "Sony gn88d" at all. I see multiple large schematics that I can't read, and I am not sure what they would tell me. And what sort of input connector would be available for a 5.1 surround sound audio connection??My TV has a fiber-optic output for those signals. Does your audio device have a fiber optic input??

Really, you have not provided enough information for anybody to understand what is requested. It is perfectly clear to you, maybe, but I am not able to read minds, especially at a distance.
