How to fix laptop sound loss

Check speaker and headphone volume

Sometimes when working on a laptop, we accidentally press the wrong function keys, causing the speaker volume to decrease or turn off completely. If your laptop speakers are muted, check the volume on the speakers on the computer to make sure they are working. If the speaker icon on the taskbar has an X (Off), turn it back on.

If you are using headphones or external speakers, plug them back in or check the power supply to make sure they are working. If necessary, use them with another device to check if it is faulty.

Restart laptop

Resetting the computer is a way to fix many errors on computers and laptops related to software. If you suspect that your laptop is having a software conflict or because you have just installed some new software, try restarting the computer to see if the problem of the laptop speaker not being able to make sound is resolved.
