Why Is My Audio Out of Sync? (And How to Fix It)

You're watching a movie, and you notice something is "off." The actor's lips move, and a fraction of a second later, you hear the words. This audio sync (or latency) issue is a common problem that can make streaming unwatchable.

Here’s what causes it and how to fix it.

What Causes Audio Sync (Latency) Issues?

This problem is almost always a client-side issue, meaning it's happening on your device, not with the provider. The video and audio for a stream are sent as two separate packets of data. Your device (Firestick, Android Box) must "decode" both packets and play them at the exact same time.

Sometimes, the video packet is more complex and takes a few milliseconds longer to decode than the audio, causing the audio to play first. This can also be caused by Bluetooth speakers, soundbars, or AV receivers that add their own processing delay.

How to Fix Audio Sync Problems

Fix 1: The Quick Fix (Change Channels and Come Back)

The simplest solution often works. Change the channel, wait for it to load, and then change back. This forces your player to re-sync the audio and video streams from scratch and often clears the issue.

Fix 2: Check Your IPTV Player Settings

Some IPTV players have settings that can cause this.

• Check Hardware vs. Software Decoder: In your app's settings, you may see an option for "Decoder." Try switching from "Hardware Decoder" to "Software Decoder" (or vice-versa). One may be more stable for your specific device.
• Buffer Size: If you're using a player like TiviMate, try increasing the buffer size in the settings.

Fix 3: Adjust the 'Audio Offset' Manually

Many advanced players (like VLC, Perfect Player, or TiviMate) have a built-in feature to fix this.

1. While the channel is playing, open the Audio Options or Settings.
2. Look for a setting called "Audio Delay" or "Audio Offset".
3. If the audio is ahead of the video (you hear it first), add a positive delay (e.g., +100ms).
4. If the audio is behind the video (you see it first), add a negative delay (e.g., -100ms).
5. Adjust this number until the audio and video are perfectly synced.

Fix 4: Check Your TV's Audio Settings (Soundbar/AVR)

If you are using an external soundbar or AV Receiver, your TV may have its own "Audio Delay" setting. Check your TV's main Sound Settings menu. If this setting is misconfigured, it will affect all apps, not just IPTV.

Fix 5: Reboot Your Streaming Device

A full reboot (unplugging the power for 60 seconds) can clear the temporary processing files on your Firestick or Android Box and resolve many minor glitches, including audio sync.
