Viber sound not working

Test your speakers first

Press Test my speakers above. If you hear the left and right sounds here, your phone or computer can play sound and the problem is inside Viber: its volume, its output device or a call setting. If you hear nothing on this page either, fix the device first with the Android, iPhone, Windows or Mac guide.

Quick checks

• Turn Bluetooth off for a moment. Calls and sound often go to earbuds in their case, a smartwatch or a car that is still connected.
• Tap the speaker button in the call if the sound is too quiet from the earpiece.
• Close other calling apps. A WhatsApp or Teams call in the background can keep the audio.
• Update Viber: old versions of Viber Desktop in particular lose sound after system updates.

Viber sound not working on Android

1. Press a volume button, then tap the ⋮ or settings icon next to the slider. Android has separate sliders for Media, Call, Ring and Notifications: raise the one that matches what you cannot hear.
2. Some phones (Xiaomi, Huawei, Oppo, Vivo) have a battery saver that stops Viber in the background. Calls then connect late or without sound. Set Viber's battery use to Unrestricted in Settings › Apps › Viber › Battery.
3. Notification sounds for messages are in Viber › More › Settings › Notifications and in the Android notification settings for Viber. Check both.
4. On Samsung, check Settings › Sounds and vibration › Separate app sound and remove Viber from it.

Viber sound not working on iPhone

1. During the call, press the volume up button. Call volume on an iPhone is separate from music and video volume, so it can be very low even when other sounds are loud.
2. Tap the audio button in the call and choose iPhone or Speaker.
3. If a call connects but you never hear the other person, end it, close Viber in the app switcher and call again. If it keeps happening, back up your chats in Viber's settings and reinstall the app.

Viber sound not working on Windows

1. Open Settings › System › Sound and, under Output, choose the speakers or headphones you want. Windows often switches to a monitor (HDMI or DisplayPort), a headset or a virtual device.
2. In Viber Desktop, open Settings › Audio & Video. Under Output, choose the speakers or headphones and use the test sound. Viber keeps its own output choice.
3. Open Settings › System › Sound › Volume mixer. Check that Viber is not muted or set to zero there, and that its Output device is Default or the speakers you use.

Viber sound not working on Mac

1. Open System Settings › Sound › Output, select the speakers or headphones you want and check that Mute is not ticked. AirPods and displays connected over HDMI often take over the output.
2. In Viber, open Settings › Audio & Video and pick the output device.
3. Quit Viber completely and open it again after connecting or disconnecting headphones.
