Check that Do Not Disturb mode is disabled

There are many users who activate, through carelessness or error, the Do Not Disturb mode (Do not disturb, in English), and they think that the speaker is not working since it does not emit any sound or alert when new notifications arrive or calls come in. But luckily, This mode can be easily and quickly deactivated via the settings or the control center., which is the one that appears when you pull down the notification bar twice. But, before explaining how to deactivate this mode, let's see what this moodo consists of...
Do not disturb mode has the function of remove alerts and sounds from your phone when it is on. This way, the Android phone will not display notifications via pop-ups, nor will it play notification sounds. This is specially designed for users who want to concentrate on a task or do not want pop-up notifications or notification sounds to interrupt the use of a particular app or game.
First, you need to check that Do Not Disturb mode is indeed activated. If this is the case, the mobile speaker will not work, except in applications and games where there is sound. To do this, simply pull down the notification bar twice until you reach the section Control center. This is usually where the Do Not Disturb button is located. You just need to press it once to deactivate it.
You can also turn off Do Not Disturb mode through settings, entering the section of Sounds and alerts. On some Android phones, depending on the Android version, the customization layer and the mobile model, this can be found in the section of Notifications

Make sure the speaker vents are not obstructed or wet

If your Android phone's speaker is not working, It may be due to some obstruction in the speakers. If your phone has two speakers, check that both of them are not working. If only one of them is not working, it is most likely due to the above. Likewise, if neither of them are making sound, they may be presenting the same problem.
This being the case, You should clean them with something fine enough to get into the speaker slots. Try to remove as much dirt and particles as possible to free up the speaker output.
Now, if the case is that these are wet, either due to a water spill or accidental immersion, The first thing you should do is dry the phone and, therefore, the speakers. Turn off your phone in the meantime, so that the speakers don't suffer permanent damage while they dry. Once they're free of moisture, turn on your phone and try testing them to see if they work.
Restart the mobile

It never hurts to restart your Android phone to see if the speakers return to normal. Therefore, if you haven't done so yet, Restart it and check if the speakers start working and making sound again. To do this, open a video or play some audio. And to restart your phone, just hold down the unlock button until the option to restart the device appears on the screen, without further ado.
