First of all
Volume level in the player and system
First, you need to check if there are volume restrictions in the operating system. For this:
- Android OS: “Settings” - “Sound”
- Apple iOS OS, Windows 10: “Settings” - “Music” - “Volume Limit”
Launch any media file and try adjusting the volume level. This can be done both in the audio player interface and using hardware buttons on the case.
Reboot
Sometimes the sound disappears when the software freezes or errors. To restore, just reboot the device.
No sound on tablet
If there is no sound on a tablet with Android OS, the reasons may also be from the list suggested earlier. When using headphones, the sound may disappear if the headset breaks or the audio jack is clogged. It's easy enough to check: insert other headphones or use the headset with another device. In any case, such problems can be solved quite simply. The audio connector can be wiped with a cotton swab moistened with alcohol. If replacement is necessary, the cost of such repairs will also be insignificant, and you will still have to buy new headphones.
Mechanical problems
Speakers
To check the speakers:
- Connect the headphones, start watching a movie, and pull out the plug.
- Try making a call and turning on speakerphone.
If the audio track is played only in headphones, but not in external speakers, contact a service center for diagnostics and repairs.
Connector
A broken audio jack is a common cause of no sound on a tablet. Oxidation of contacts occurs from contact with water, dirt, or even simply high ambient humidity. First, the sound begins to rattle, stutter, becomes strange, and then it may disappear completely. In this case, cleaning the connector with a special liquid or alcohol will help. Before turning on the tablet after such a procedure, it is necessary to dry the contacts thoroughly.
Due to careless handling (strong mechanical impact), the plates inside the port shift and bend. Here it is better to contact a service center to bend the contact or replace the entire connector. This affects not only cheap tablet PCs (Oysters t104w 3g, Finepower N1, Irbis TW73, 4Good T101i, Dexp Ursus M110, Digma Optima 1101, Prestigio MultiPad Visconte V PMP1012TE), but also more expensive brands (Asus transformer pad, Lenovo YOGA Tablet 2, Samsung Galaxy Tab a8, Acer Aspire Switch 10, HUAWEI MediaPad T5 10 16Gb LTE).
The cable broke
If your gadget's volume control buttons are installed not on the motherboard, but on a separate plate with a cable, then over time and with careless handling, the conductive plate becomes deformed and requires replacement. The difficulty is that it is not always possible to find a genuine (read original) part, and it is not always available in the service department. The technician may suggest that you re-solder it, but we do not recommend doing so. Or replace it with the most similar analogue from another model.
Sound module burned out
If the sound module on the motherboard is damaged, audio recordings will not be played either in headphones or speakers. Self-repair is highly undesirable - contact qualified specialists. Since a soldering station is required for desoldering and installing a new radio component. A regular soldering iron cannot carry out such a procedure without dire consequences for the equipment.
Why there is no sound on the tablet when watching a movie - reasons and solutions to the problem
Very often we use tablets as multimedia players. High-quality high-definition screens are just begging to be used as a portable cinema. However, the fun can be ruined by the lack of sound (even if you're watching an old silent movie, yes!)
If there is no sound when watching a movie on your tablet, this can most often be corrected using software methods. However, there is a more unpleasant situation when the headphone jack or speaker of the tablet fails.
In any case, you shouldn’t immediately rush to the workshop with a tablet and money. To begin with, you can make an initial diagnosis yourself and find out what exactly your problem is.
The most common reasons for no sound:
Launch the same video file through the same player, connecting headphones. If there is sound in the headphones, try playing a YouTube video or music file through the player, listening to it through an external speaker. If the external speaker does not produce any sounds at all, you need to go to the workshop.
Even if the worst happens and the tablet’s hardware is damaged, now you will know the problem and can go to the service center fully armed. You will be able to compare the cost and timing of work in different companies and choose the best option for yourself.
OS errors
Application errors
If, after checking all mechanical components, the sound still does not appear, the problem may be with installed applications. This is indicated by the absence of audio signals in certain functions: notifications from social networks, SMS or alarm clock.
This problem is mainly associated with the installation of software that speeds up the performance of the OS. Often when background processes are closed, the audio signal is also turned off. Rebooting the tablet PC and adjusting the software settings will help here.
Codecs are gone
Free versions of video players do not have all the necessary codecs to play all types of audio and video formats: avi, mkv, wav, mp3, aac, wma, flac, alac, etc. In this case, you will have to find and install them additionally. But it’s worth knowing that some of them only work with a certain class of processors, so you’ll have to look for a universal set that’s suitable for everyone.
This problem may also occur after a software update. In this case, you can try reinstalling the player. However, if the manufacturer decides to make this format paid, this will not help.
Try free VLC player, it is available for all platforms, iOS, Windows, Android. Look for the official application in the App Store and Play Market.
The player requires reinstallation
Do not neglect installing updates that are periodically offered by the manufacturer. At some point, the player will simply stop playing files due to the lack of certain parameters and capabilities. Completely uninstall and reinstall the player again: all current updates will be downloaded automatically.
Viruses
To expand the capabilities of the Tablet PC, owners install uncertified utilities that provide access to Root rights. Thanks to them, you gain full access to the operating system and can perform destructive operations. For example, try to increase the memory and accidentally delete system files that are responsible for the correct operation of the tablet. To recover deleted data, you will have to use a third-party application.
Often, along with such a utility, a virus is loaded that has full access to the OS and unlimited capabilities: disabling and deleting functions, making calls and sending SMS, posting personal data on the Internet.
There is only one solution to this problem - uninstall the software and perform a full scan with a good antivirus. The most extreme measure is to reset the device to factory settings or reflash the device.
System glitches
If you had to force a restart or completely shut down your Tablet PC, this may cause the operating system or a specific application to malfunction. In this case, check through the tablet settings to see if the audio player’s microphone access permissions have changed.
If the problem is unauthorized closure of a system process, a classic reboot of the operating system (applies to Windows, Android and iOs) most often helps, or in extreme cases, a complete reset or flashing.
Chinese budget models more often suffer from software failures (Dexp, Dns, Irbis, Philips, Prestigio multipad, Digma, Texet, Tesla).
Crooked firmware
You may have installed custom firmware, which has certain shortcomings and therefore there is no sound. Flashing the official, stable version of the operating system installed from the manufacturer’s website will help.
Increase sound level
Engineering menu
If the audio sound on your device has deteriorated: it has become quieter or disappeared completely, using the engineering menu you can perform advanced configuration of the device, including changing the bad and weak sound on the tablet, turning down or increasing the volume.
It’s worth noting right away that access is not available on all devices.
There are several ways to enter the special. menu:
- Entering a code of the form *digits*# in dialing mode. It is unique for all manufacturers; we recommend that you search separately for your model.
- Software - can be found in the Play Market.
- Developer mode. The manufacturer could limit access to the engineering menu, then you will have to be content with the minimum functions of this mode.
If you still managed to open the advanced functionality menu on Android, you need to go to “Hardware Testing” - “Audio” and select the desired speaker operating mode:
- “Normal Mode” - standard;
- “Headset Mode” - external audio devices;
- “LoudSpeaker Mode”—activate the loudspeaker;
- “Headset_LoudSpeaker Mode” - loudspeaker when a Bluetooth headset or headphones is running;
- "Speech Enhancement" - telephone communication.
After selecting the required parameter, go to the “AudioModeSetting” - “Type” section:
- “Sip” - on the Internet (in the browser - Yandex, Chrome, in applications - Skype, Viber, WhatsApp, Odnoklassniki, YouTube, TubeMate);
- “Sph” and “Sph2” - all speakers;
- “Media” - all media files;
- “Ring” - incoming calls;
- "FMR" - radio.
In the “Level” section, use the volume buttons to set one of seven levels. You can reduce or increase the sound.
In the “Value is 0-255” section, you can set the power and maximize the sound, and partially remove background noise.
To save and apply all changes, click “Set”.
Attention! Menu items on different devices may differ from those shown above.
At maximum gain, the sound may deteriorate and noise and rattling may appear.
It is worth remembering that any independent change in the manufacturer’s engineering settings entails removal from warranty service and repairs and can lead to a serious malfunction of the device.
Resoldering the audio processor
It is better not to repair or disassemble the device yourself if you are not confident in your own abilities. But if you still decide:
- Disassemble the gadget;
- Find the speakers and determine how they are attached to the motherboard: using two wires or simply adjacent to it with contacts;
- For wired connections, check them for fractures and breaks. If necessary, restore the integrity of the wires;
- Very carefully unsolder the speaker and check the resistance with a multimeter or ohmmeter. A zero indicator, like an infinite one, indicates a malfunction;
- Replace element if necessary.
Finding an improved original speaker is quite difficult, and from well-known brands (iPad, Lenovo, Asus, Acer, Huawei, Samsung Galaxy Tab 4) it can be quite expensive. Then you can use the Chinese analogue with enhanced characteristics.
If this does not help, the mother chip is most likely malfunctioning. Such repairs require certain equipment and special knowledge, so you should contact a service center.
Causes of the problem
Of all the errors, a separate category of system failures can be distinguished. They happen for a variety of reasons, but usually it is one of several scenarios described below.
Main factors of breakdowns:
- Manufacturing defects. If the problem appears during the warranty period, the best option would be to take it to a service center or exchange the phone for a new one.
- Unsuccessful flashing. The procedure has many nuances and, if used improperly, can turn your smartphone into a useless pile of electronics.
- Installation of "left" applications. For the Android OS, there is an excellent opportunity to download proven applications, games and other software from the Google Play service. Using other resources is very risky, and even more so installing unverified programs on your phone.
- Non-critical failures in the operation of the gadget, which can be resolved by rebooting the device. It is also advisable to remove the battery after turning it off and keep the phone in this state for some time.
In cases where there is no sound on Android, you need to check your phone settings and also eliminate the possibility of system errors. If it is impossible to independently determine the breakdown, the best option would be to contact a specialized workshop.
Recommendations and lifehacks
There are several other ways to enhance the quiet sound of your tablet:
- Using an external device
— Headphones with an amplifier (rarely available anywhere);
- External Sound Card;
— Bluetooth headset with sound processor;
— Mobile speaker with connection via bluetooth or AUX;
- Download additional software - audio amplifier. The most famous is Volume+, but there are others.
How to change the factory settings through the engineering menu is described above, but do not forget that such intervention may lead to failure of the device.
