You’re scrolling through Facebook, excited to watch that funny video your friend shared, but there’s no sound even though the video is playing perfectly. This frustrating issue affects millions of mobile users daily and can usually be fixed in under two minutes with the right approach.
Step-by-Step Fixes
Step 1: Check Your Phone’s Silent Mode
The quickest fix that solves this problem for most people. Look at the side of your iPhone for the physical mute switch – if you see an orange line, your phone is on silent. For Android users, press the volume up button and check if the media volume slider appears at zero. Simply flip the switch or increase the volume to restore sound instantly.
Step 2: Unmute the Facebook Video
Facebook videos often start muted by default to prevent unexpected loud sounds in public places. Look for the speaker icon on the video player – it’s usually in the bottom right corner. If there’s a line through the speaker, tap it once to unmute. The icon should turn white or blue, indicating sound is now active.
Step 3: Force Close and Restart the Facebook App
Sometimes the app gets confused and needs a fresh start. On iPhone, swipe up from the bottom (or double-click the home button on older models) to see all open apps. Swipe up on Facebook to close it completely. Android users can access recent apps by tapping the square or three-line button, then swipe Facebook away. Wait five seconds before reopening the app.
Step 4: Check Facebook’s In-App Sound Settings
Open Facebook and tap the three horizontal lines (menu button). Scroll down to “Settings & Privacy” then tap “Settings.” Look for “Media” or “Videos and Photos” depending on your app version. Make sure “Videos Start With Sound” is toggled on. This setting is ideal for users who want consistent audio playback without manually unmuting each video.
Step 5: Clear Facebook App Cache (Android Only)
Go to your phone’s Settings > Apps > Facebook > Storage. Tap “Clear Cache” but avoid “Clear Data” which would log you out. This removes temporary files that might be causing audio conflicts. iPhone users don’t have this option as iOS manages cache automatically.
Step 6: Update or Reinstall Facebook
Visit your device’s app store and search for Facebook. If you see an “Update” button, tap it. If the problem persists after updating, delete the app completely by holding the Facebook icon until it wiggles (iPhone) or through Settings > Apps (Android). Reinstall fresh from the app store. This method is best used when other solutions haven’t worked.
Likely Causes
Cause #1: Bluetooth Connection Interference
Your phone might be sending audio to a connected Bluetooth device like headphones or your car stereo. Check by swiping down from the top of your screen to access quick settings. If the Bluetooth icon is highlighted or blue, tap it to see connected devices. Disconnect any audio devices or turn Bluetooth off completely. This issue is especially common in 2025 with the proliferation of wireless earbuds and smart speakers.
Cause #2: iOS or Android System Audio Glitch
Operating system bugs can block audio from specific apps while allowing others to work normally. You can verify this by playing a YouTube video or music app – if those have sound but Facebook doesn’t, it’s likely a system-level issue. Restart your phone by holding the power button and selecting restart. This clears temporary system files and reestablishes proper audio routing.
Cause #3: Facebook Server-Side Audio Problems
Sometimes Facebook experiences partial outages affecting video sound for certain regions or user groups. Check DownDetector or search “Facebook sound not working” on Twitter/X to see if others report similar issues. These problems typically resolve within hours without any action needed from your end. Not recommended when you need immediate access to video content with sound.
When to Call an Expert
Consider professional help if videos have no sound across all apps, not just Facebook. This indicates potential hardware damage to your phone’s speakers or audio chip. Visit your carrier’s store or an authorized repair center if your device is under warranty.
Also seek expert assistance if you’ve recently dropped your phone in water or noticed crackling sounds during calls. These symptoms suggest physical damage that software fixes cannot resolve.
