Fix IPTV Audio-Video Sync

Audio and video out of sync? Lips not matching the words? Fix it in minutes with these proven solutions.

Step-by-Step Fix

Restart the Stream

Stop the current channel and restart it. Temporary desynchronization often resolves when the stream is refreshed.

Switch Audio Track

Many channels offer multiple audio tracks. Switch to a different track and back — this forces the audio decoder to resync.

Change Video Decoder

Switch between hardware and software decoder in your IPTV app settings. Hardware decoding can cause sync issues on some devices.

Adjust Audio Delay

Apps like TiviMate have an audio delay setting. Adjust it in increments of 50ms until audio matches video.

Clear App Cache

Clear the IPTV app cache to remove corrupted buffered data that may be causing the desync.

Restart Your Device

A full device restart resets all audio and video pipelines, clearing any accumulated drift.

Device-Specific Tips

Fire Stick / Android

Switch to software decoder in app settings. Hardware decoding on lower-end devices often causes sync drift over time.

Smart TV

Check your TV audio output settings. Some TVs add processing delay. Disable sound enhancements or Dolby processing.

FAQ

Why is my IPTV audio out of sync?

Audio sync issues are usually caused by video decoder settings, network latency, or app cache issues. Hardware decoding can process audio and video at different speeds on some devices.

How do I adjust audio delay in TiviMate?

During playback, open the player settings menu, find Audio Delay, and adjust in 50ms increments. Positive values delay audio, negative values advance it.

Does internet speed affect audio sync?

Yes. Inconsistent internet speeds cause packets to arrive out of order, leading to desynchronization. Use wired Ethernet for the most stable connection.

Why does sync only happen on certain channels?

Different channels use different encoding formats. Some formats are more prone to sync issues with certain video decoders. Try switching your decoder type.
