Be careful, using this method is often effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone or tablet. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if after this the problem is not resolved, see Method 2.

There is no sound in the smartphone (phone) or tablet on Android platform. What to do and how to fix it?

Smartphones and tablets running operating system, at this stage of technology development and wireless networks, are primarily multimedia devices. Millions of users around the world use their mobile gadgets to watch videos, listen to music and communicate online. in social networks and messengers. However, a situation may arise when you have no sound when watching videos or movies. We will tell you what this problem may be related to and how to solve it.

Make sure the problem is in the video

Before starting any manipulations, you should find out whether the problem is only the lack of sound in the video or there is no sound at all. Try turning on music or going into settings and playing system sounds. Perhaps you just accidentally installed silent mode or lower the volume to minimum. If there is no sound everywhere (it is not in music, settings, video), then it is likely that the problem lies in the dynamics of the smartphone.

Lack of required codecs

Just like on a computer, programs for viewing video files on Android require special codecs for correct audio processing. You can try installing free codec packs from the official store Google applications Play.

Lack of AC3 codec

On personal experience I can say that most often there is no sound in large .mkv files in which the sound is encoded in AC3 format. The simplest and in a fast way The solution to this problem is to install the program. When playing a video file in this player, there is almost always sound.

If all of the above methods did not help and there is no sound in the video, then you can proceed to drastic methods - resetting the settings and flashing the smartphone. However, before doing this, we strongly recommend checking whether the audio track is present in your video; try playing it on your computer.

The owners of tablets running operating systems face this problem the most. Android systems. But as practice shows, the overwhelming number of cases related to tuning or lack of sound can be corrected. The most common problems related to setting up sound on a tablet lead to software or to a breakdown on the part of the device, as well as often to the usual inattentiveness of the user. In particular, we can highlight two main points related to the presence of problems with sound: the sound is completely absent or the sound is present, but not everywhere (for example, in the alarm function everything is played, but when using a video player there is no sound).

There is no sound at all

Changing the volume level. (this action can be performed either using the volume rocker, or using a special menu item in the tablet). Go to the Settings menu, find the Sound item, then Volume. The main thing here is to set the Volume level to the maximum value and everything connected with it. Now you need to launch the game, no matter what, the main thing is that it has sound effects, all this is necessary to test the changes. (please note that you need a game!)
If after you have completed all the steps recommended in the paragraph above and this has not given any changes, then you should ask yourself: is the sound missing from the speakers themselves or does it not want to appear only when the headphones are turned on? If after this question it turns out that the problem is in the headphones, then with a 100% probability they simply played their role, and it’s time to replace them with new ones.
If the problem is still present, then I advise you to remember whether you used programs or applications to clean system memory in the startup list when you started the device. There is a possibility that you simply could have closed the process that is responsible for the names of the sound in the device. With such a problem, it often happens that I pressed something without knowing what. In such a situation, we can only recommend one correct option, resetting the tablet settings to their original form. This procedure can be done by finding an item in the system settings, it is called Restore and reset, the main thing here is not to forget to uncheck the Clear SD card item. After you have fulfilled all the necessary conditions, all that remains is to activate the Device Recovery and Rollback function. The saddest thing about this feature is that you will have to say goodbye to all programs that are not standard for your device. The positive aspect of this action is that if the lack of sound was truly due to a hardware error in the system, then the probability of sound appearing is almost 100%.
It is also worth paying attention to the fact that the tablet could have been flooded or dropped. In this case, it would be wiser to take the tablet to a special institution or specialist for diagnostics.
