Samsung Galaxy S7 does not ring externally while headset cable plugged in connector

I use a Samsung Galaxy S7 with /e/OS 0.18 .
I miss that the phone rings externally while the headset cable is plugged in the connector. Sometimes I keep the headset plugged in although I do not wear the headset over the ears. In case someone then calls me I do not hear the phone ringing, because the rings can only be heard via headset. So I would prefer that the phone also alarms using the internal speaker.
I it possible to activate this somehow?

Thank you in advance.
