Can you connect speakers via RCA?

Question

Acustic systems

It just so happens that I have two BT H/K speakers and need to wire them to the TV because of the insane latency.

The speakers have a 3.5 connector. You need to connect via HDMI Arc. Through the optics, as I understand it, you can not adjust the volume with the remote control.

I thought it was possible to connect from two 3.5 to one, but from those splitters that I saw, they make one stereo - 2 stereos, i.e. not divided into left and right channels.

The converter has two RCA outputs.

Essence of the question. Will it be possible to buy two adapters 3.5 - 2 x RCA (l / R) and connect each column to the converter? As a result, one RCA from each adapter will be involved, while the others will simply hang.

This is not strong and could call something wrong. Thanks in advance.
