Problem with speakers on the laptop. Does anyone know solution?

I connected my laptop (the screen is broken) to a monitor using an HDMI cable. Now I don't hear any sound from my laptop, even when I use headphones. Can someone explain how I hear sound again?

Search for the sound settings there you can choose which audio device should be used. Now the audio signal will probably be sent to your monitor via hdmi, which is why you won't hear anything

OMG thank you I was desperate
