TikTok Videos Have No Sound — Audio Not Working

What Does This Error Mean?

No sound on TikTok is almost always a simple settings or hardware issue. Check that your phone is not muted and the TikTok volume is turned up. On iPhone, the side switch being on Silent mode is a very common cause.

TikTok for iPhone

Common Causes

Phone is on silent or mute mode
Volume turned down to zero inside the TikTok app
Headphones are connected but no sound is coming through them
The video creator muted the audio when posting
A bug in the TikTok app after a recent update

How to Fix It

Check that your phone is not on silent — turn the volume up using the side buttons.

On iPhone, there is a physical mute switch on the left side of the phone.
While a TikTok video is playing, tap the screen to see the volume icon.

If the speaker icon has a line through it, tap it to unmute the video.
Disconnect any headphones or Bluetooth speakers and test again.

Sometimes the phone routes audio to a device that is not nearby or turned on.
Force-close the TikTok app and reopen it.

This resets any app-level audio glitch that may have occurred.
Clear the TikTok app cache if the issue persists.

Go to Profile, tap the three-line menu, go to Settings, then tap Clear Cache.

When to Call a Professional

Sound issues are almost never serious enough to need outside help. If audio is broken across all apps on your phone, the hardware may need repair.

Frequently Asked Questions

Why does only one TikTok video have no sound?

The creator may have uploaded the video without audio. This is not a bug — it is intentional on that specific video.

Why did TikTok sound suddenly stop working after an update?

App updates can sometimes reset audio settings. Force-close the app, check your phone volume, and reopen TikTok.

Why can I hear TikTok sound through headphones but not my speaker?

Your phone's speaker may be blocked or damaged. Try playing audio in another app — if that also has no sound, the speaker needs repair.
