The situation when Viber stops making sounds when receiving incoming messages or calls is one of the most common problems of users Android. This may happen suddenly after a system update, changing power saving settings, or accidentally switching Do Not Disturb mode. The absence of a sound signal often leads to missing important messages from colleagues or loved ones, which creates serious discomfort in everyday communication.
To restore the functionality of the messenger, you need to consistently check several levels of settings: from the system parameters of the smartphone to the internal settings of the application itself. In this article, we will analyze in detail each stage of diagnostics and configuration so that you can be guaranteed to return sound to Viber on your device.
Checking system notification settings
First of all, you should make sure that the operating system Android does not block notifications from the messenger at the global level. Modern versions of the OS have a flexible application rights management system, where you can turn off the sound for a specific app, leaving other parameters active. Go to Settings → Applications → Viber and find the section Notifications.
In the menu that opens, make sure that the “Allow notifications” switch is active. However, this is not enough: you need to click on the “Notifications” line itself to expand detailed categories. Here it is important to check the status of the “Messages” and “Calls” channels. If there is a crossed out speaker icon next to them or the slider is turned off, then the sound will not play, even if the media volume is turned up to maximum.
Pay attention to the parameter Sound inside the message category. By default, it may be set to "Mute" or "System Default Sound". For reliable operation, it is recommended to select a specific melody from the list to eliminate software conflicts. Also check if the “Silent Notifications” mode is activated, which hides the content and turns off the sound.
⚠️ Attention: In some shells (for example, MIUI or EMUI), notification settings may be hidden in the additional submenu “Advanced” or “Manage Notifications”. If you do not see the sound switches right away, carefully examine all the nested application menu items.
If the sound does not appear after changing the settings, try restarting your smartphone. This will update the system notification services and apply the new settings correctly.
Configuring a sound profile inside the Viber application
Even with the correct system permissions, internal settings Viber can override the behavior of the sound. Open the application, go to the More → Settings → Notificationssection. Here is the control center for all messenger sound signals. Make sure that the switch Notification sounds is in the active position.
Click on the “Notification Sound” item to select the desired melody. The list can contain both standard system ringtones and files you downloaded to the device memory. If you want to use a unique sound for important contacts, this is also configured in this section, but requires an individual approach to each chat. Don't forget to save changes if the interface requires confirmation.
Special attention should be paid to the call settings. In the same menu, find the section Calls and check the “Ringtone” option. Often, users accidentally set a silent profile specifically for incoming calls, while messages arrive with sound. Here you can also set up vibration by selecting one of the preset patterns or creating your own.
Adjusting volume and sound channels
In the system Android there is a division of volume into several independent channels: media, call, alarm clock and notifications. The problem with Viber often lies in the fact that the “Notifications” or “System Sound” channel is set to the minimum value, while the media volume (music, video) is at maximum. To check this, press the volume up button on the side of your smartphone.
When the volume bar appears on the screen, press the gear icon or the three dots next to the slider to expand the full mixer. Find the slider with the bell icon or the words “Notifications” / “Ring” and raise it to a comfortable level. In some versions of Android, notification volume settings are placed in a separate menu Settings → Sound and vibration → Volume.
It is important to distinguish between ringer volume and notification volume. If you can't hear an incoming call in Viber, adjust the “Ring” slider. If you don’t hear messages, click the “Notifications” slider. In Do Not Disturb mode, these channels can be completely muted by software, regardless of the position of the physical sliders.
| Sound type | What it is responsible for | Where to adjust |
|---|---|---|
| Media | Video, music, sounds in games | Volume buttons during playback |
| Ring (Ring) | Incoming voice calls | Settings → Sound → Ring volume |
| Notifications | Chat messages, system alerts | Settings → Sound → Notification volume |
| Alarms | Alarms | Clock application or sound settings |
Remember that the physical volume button only changes the currently active channel. To configure notifications, it is better to use the software mixer in the settings.
The influence of Do Not Disturb mode and power saving
Mode Do Not Disturb (Do Not Disturb) is a common reason for the absence of sounds. When activated, the system blocks all sound and vibration except for permitted exceptions. You can check the status of this mode in the notification shade or in the Settings → Sound and vibration → Do not disturbsection. Make sure the mode is turned off or configured correctly.
If you need to leave the mode active but still receive messages from loved ones, set up exceptions. In the Do Not Disturb settings, find the “Applications” or “Calls and Messages” section and add Viber to the priority list. You can also allow repeated calls from the same contact within a short period of time, which is useful in emergency situations.
Aggressive power saving settings can “kill” the messenger process in the background, preventing timely notifications and sound playback. Go to Settings → Battery → Battery optimization (the path may vary depending on the model). Find Viber in the list and select the “Do not optimize” or “No restrictions” option. This will allow the application to work in the background without restrictions.
⚠️ Attention: The energy saving settings interface is very different on smartphones from different manufacturers (Samsung, Xiaomi, Huawei). If you cannot find the item you need, use the search inside the settings menu for “battery” or “optimization.”
Why does the sound disappear after a reboot?
Some smartphone manufacturers reset permissions to run in the background after a reboot to save resources. In this case, you need to re-issue permission to autorun in the application settings.
Selecting and installing your own ringtone
Standard ringtones can quickly get boring, and many users prefer to set their own compositions for messages in Viber. To do this, the audio file must be saved in the device memory in the format MP3 or OGG. It is advisable to place the file in the folder Notifications (for messages) or Ringtones (for calls) in the internal storage so that the system will automatically detect it.
After placing the file, go to the notification settings Viberas described in the previous sections and select “Notification sound”. In the list that opens, scroll down to the My Sounds or Local Files section. Your composition should appear there. If the file is not displayed, try clearing the application cache or rebooting your phone to update your media library.
When choosing a melody, consider its duration and volume. Tracks that are too long may be cut off and quiet recordings may be inaudible in noisy environments. The optimal duration of the sound signal for the message is from 2 to 5 seconds. For calls, you can use longer fragments, but make sure that the beginning of the melody is loud enough and recognizable.
- 🎵 Make sure that the melody file is not protected by DRM copyright, otherwise the system will not be able to play it.
- 📁 Name files in Latin to avoid problems with encoding and display of names in the list.
- 🔊 Check the volume of the file in any audio player before installation so that it is not too quiet.

Solving sound problems: reset and updates
If all of the above methods did not help, there may be a software failure in the application. Try clearing the cache and data Viber. To do this, go to Settings → Applications → Viber → Storage and press the button Clear cache. If this does not help, you can click “Clear data”, but remember that this will delete the chat history if it is not saved in the cloud or on the SD card.
Make sure that you have the latest version of the application installed. Developers regularly release updates that fix bugs with sound and compatibility with new versions Android. Go to Google Play Market, find Viber and check for the “Update” button. Also check for updates to your smartphone's system software, as problems may be at the operating system level.
In extreme cases, a complete reinstallation of the application will help. Before doing this, be sure to create a backup copy of your chats in settings Viber (Settings → Account → Backup). After uninstalling and reinstalling the application, restore the copy. This often resolves deep conflicts in configuration files.
⚠️ Attention: Before clearing data or reinstalling the application, be sure to back up your correspondence, otherwise you may permanently lose your message history and media files.
If the sound only works in headphones or only through the speaker, check the sound output settings in the "Special Features" section or through the engineering menu, if you have access to it.
Frequently asked questions (FAQ)
Why does the sound in Viber only work when the screen is on?
This is a classic sign of the operation of an aggressive energy saving system. The system puts the application to sleep when the screen is off. It can be solved by disabling battery optimization for Viber in the smartphone settings and granting permission to work in the background.
Is it possible to set different sounds for different contacts in Viber?
Yes, it is possible. Open a chat with the contact you want, tap their name at the top of the screen, then go to Notifications and select Message Sounds. There you can set an individual melody only for this interlocutor.
Why did the sound in Viber disappear after an Android update?
With a major system update, the access rights and audio channel settings may be reset to factory settings. You need to re-check notification permissions and make sure that the audio channels are not set to “Silent” mode.
How to enable vibration if there is no sound?
In the Viber notification settings (both system and internal) there is a separate “Vibration” switch. Make sure it is active. Also check if vibration is turned off in the general sound settings of your phone.
Does data saving mode affect the sound of notifications?
The traffic saving mode itself does not mute the sound, but it can block background data transfer. If the message does not arrive on time because the Internet is blocked, then the sound will not sound. Add Viber to the exceptions of the traffic saving mode.
