I have a Sony Bravia that only has optical out and 2.5mm headphone jack for output.
A new LG Stereo my wife has is 2.1 but only analog in.
What kind of options do we have?
I found an old 2.55 in a draw with yellow/red rca outputs. I tried that and theres a hum coming out of each speaker, loudest from whichever goes into the steroes white jack.

I forgot the LG stereo also has Bluetooth capability. I just tried with my galaxy phone and worked good.
Is there a low latency optical to bluetooth solution perhaps?
