Nintendo switch without sound Soundbar?

My switch gets no sound at the Samsung Soundbar. The soundbar apparently has 3 outputs for sound. Optical port, an Aux port and a USB port. The Playstation 4 is connected to the optical cable and gets sound via D.IN. However, if I connect my switch via USB there's no USB port on the SOundbar. What option do I have to get sound?

I would try the AUX connection, is usually best

Unfortunately, the switch has no aux input, right?

The headphone output…
