Why do not I have a sound on my laptop?

I have an Acer Aspire with Windows 10.

The PC is not silenced.

I have also made sure that in the music player, the sound is set correctly.

I have checked the volume mixer, there I'm informed that normal sound comes from the speakers. I still hear nothing.

I've disabled the player several times and turned it back on.

I've checked, disabled and re-enabled the drivers several times, uninstalled and reinstalled and updated.

I have the latest version of Windows 10.

Even connected headphones do not work.

What can this be?

Take off the ear protection.

Did you already turn the device on and off?
