Hacking a TRRS to TRS adapter
TRRS has a few standards. The iPhone/Apple Standard, the Nokia Standard, and a rarely seen video standard. They all mix where the ground is. Your adaptor may be any one of the three. Most important is the ground on the adaptor. The shield of the three rca connectors should be electronically connected to each other, AND it should go to the ring or sleeve that matches your source device.

AFAIK, Samsung has supposedly moved from the Nokia to the Apple standard, but that might not have been implemented on your specific model devices.

Apple Standard, TRRS = L, R, G, M.
Nokia Standard, TRRS = L, R, M, G.
Other Standard might have Ground where R normally is.

In any case break out a continuity or multimeter. Until you are sure the Device ground is connected to the rca shields, it won't work properly.
