Enabling the speaker on a baofeng dm 1701

How do youi enable the speaker on a Baofeng DM 1701. Can not find anywhere in the programming software to do this.

I don’t think there is a function to turn it off? Nothing in the menus on the radio or in the software? With radios with the usual two pin headphone/mic socket there’s no need to have a function. I assume your snag is no sound through the speaker, but there IS sound through the external speaker/mic socket?
