Audio lag or desync in TiviMate usually happens because the video decoder, network buffering, or device performance can’t keep perfect timing with the audio stream.

This is especially common after app updates or when switching between codecs (HW / HW+ / SW).

Here’s everything you can do to fix it — in order of what works best.

1. Change the Decoder in Player Settings

This is the most common fix for sound delay in TiviMate.

1. Open TiviMate → Settings → Playback

2. Tap Decoder

3. Try switching between:

   • Hardware (HW)

   • Hardware+ (HW+)

   • Software (SW)

4. Return to playback and test again.

Tip: HW+ usually gives the most stable sync on Android TV and Firestick, but some older devices perform better with HW.

2. Clear TiviMate Cache and Restart

Cached files or partial playlist data can affect playback timing.

• Go to your device’s App Settings → TiviMate → Storage → Clear Cache

• Restart your device

• Open TiviMate again and reload your playlist

This refresh often resolves hidden lag or sound desync introduced by stale data.

3. Check Your Internet Speed & DNS

If your stream buffers even slightly, the audio and video can lose sync.

Use a speed test on your device — you need at least 15 Mbps stable for HD and 25 Mbps for 4K.

If speeds are fine, change your DNS to something faster and more reliable:

• Google DNS: 8.8.8.8 / 8.8.4.4

• Cloudflare DNS: 1.1.1.1 / 1.0.0.1

A faster DNS reduces packet delay and improves stream consistency.

4. Toggle Audio Track or Stream Source

Sometimes the issue is in the audio track itself.

During playback:

• Long press OK / Select on the remote → choose Audio Track

• Switch to another track (if available)

• Check if the sync issue disappears

If your playlist offers multiple stream sources, try the alternate feed — this isolates provider-side timing errors.

5. Turn Off Surround Sound or Audio Passthrough

On some Android TVs and boxes, Dolby or passthrough modes cause delays.

Go to your device’s Sound Settings and set:

• Audio Output: PCM

• Surround / Passthrough: OFF

Restart the device and test again in TiviMate.

6. Adjust the Sync Manually (Advanced)

If all else fails, use TiviMate’s built-in delay feature to manually correct audio timing.

While playing a stream:

1. Open the on-screen menu

2. Select Audio Offset (if visible in your version)

3. Increase or decrease delay until the sound matches perfectly

Make note of the offset time if it happens frequently — some users find ±200 ms fixes common desyncs.

7. Reinstall or Roll Back TiviMate

If the issue started after an update, reinstall the app completely:

• Uninstall → Reboot → Reinstall → Restore Backup

If the problem remains, consider installing an earlier TiviMate build (via the official store or backup APK).

Quick Recap

✅ Try switching between HW / HW+ / SW decoders
✅ Clear cache and restart
✅ Test alternate audio track
✅ Disable surround / passthrough
✅ Change DNS
✅ Reinstall or roll back if needed

Final Tip

If none of these steps work and audio sync issues happen only with one playlist, it’s likely a provider-side problem.

Try another playlist temporarily — or contact support to check if the stream encoding uses variable bitrates (a common cause of desync).

Closing

TiviMate remains one of the most stable players available, but like any app handling live transcoded streams, sync errors can appear occasionally.

Applying the fixes above — especially changing the decoder and clearing cache — resolves it for over 90% of users.
