To fix TiviMate audio that is out of sync, open the player menu during playback and change the audio delay a little at a time until voices match lips. If that does not work, change the passthrough and decoder settings in TiviMate. Then check the sound settings on your TV device.
What You Need
- TiviMate 5.x installed on your device
- Your TV remote
- A channel or video where people are talking, so you can watch their lips
- About five minutes
- Your soundbar or AV receiver remote, if you use one
Quick note: "Audio offset" or "audio delay" means how many milliseconds (ms) the sound is moved earlier or later than the picture. 1,000 ms is one second.
How to Fix TiviMate Audio Out of Sync: Step by Step
Do the steps in order and test after each one. Stop when the sound matches. Menu names can be a little different between TiviMate versions and devices.
- Start the channel that has the sync problem and wait 10 seconds so the stream can settle.
- Press OK on your remote to open the player panel.
- Open the audio options in the panel and look for "Audio delay" or "Audio sync".
- If you hear the sound before the lips move, delay the audio by 50 to 100 ms.
- If you hear the sound after the lips move, move the audio earlier by 50 to 100 ms.
- Watch the speaker's mouth for 10 seconds. If the gap gets bigger, you went the wrong way, so change the value in the other direction.
- Keep changing it in small steps until words match lips.
- If the player has no delay option, press Back and go to "Settings > Playback".
- Find the audio passthrough option and turn it off. Passthrough sends raw surround sound straight to your soundbar, and that can add delay.
- In the same menu, change the video decoder from hardware to software, or from software to hardware. The decoder is the part that turns the stream into a picture.
- In "Settings > Playback", set the buffer size to a larger option. A buffer is a short stretch of video loaded ahead of time so playback stays smooth.
- Restart TiviMate, then play the same channel again to test.
If a Step Fails
Sometimes the fix only lasts a few minutes, or only works on one channel. Try these checks:
- The delay resets on every channel: some channels come with their own timing. Set the delay again on that channel, or fix it on your device instead (see below).
- Sound drifts slowly over time: this often points to a weak connection. Restart your router and set a larger buffer.
- Passthrough off gives no sound: turn it back on and set your device's surround sound to "Stereo" instead.
- Software decoder makes the picture stutter: switch back to hardware. Software decoding uses more power from the device.
- Nothing works: clear TiviMate's cache in your device's app settings, then restart the device.
Why TiviMate Audio Goes Out of Sync
Audio and video come in as separate pieces of data. The player has to line them up using time stamps. When anything along the way slows one piece down, they stop lining up.
Here are the most common causes:
- Sound equipment delay: soundbars and receivers need time to decode surround sound. That can push the audio behind the picture.
- TV picture processing: motion smoothing and other picture modes slow down the video. Then the sound arrives first.
- Network trouble: lost or late data packets can upset the timing. Network World covers how delay and packet loss affect streaming traffic.
- Decoder mismatch: some devices handle certain audio formats badly in hardware mode.
- A problem in the source stream: if the stream itself is out of sync, every device will show the same gap.
A simple test: if only one channel is off, the stream is likely the cause. If every channel is off, check your device and sound setup first.
Fix Options Compared
Each fix works at a different level. This table helps you choose where to start.
| Fix | Where to Find It | Best For | How Long It Lasts |
|---|---|---|---|
| Audio delay in player | Press OK during playback, then audio options | One channel with a fixed gap | Often per channel or per session |
| Turn off passthrough | "Settings > Playback" | Soundbar or receiver setups | Stays until you change it |
| Switch decoder | "Settings > Playback" | Sync that is off on every channel | Stays until you change it |
| Larger buffer | "Settings > Playback" | Sound that drifts slowly over time | Stays until you change it |
| Device AV sync | Your device's sound menu | Every app on the device is off | Stays and works in all apps |
| Change DNS to 1.1.1.1 | Your device's network menu | Weak or slowed-down connections | Stays until you change it |
Device Sound Settings That Affect Sync
If every app on your TV has sync problems, the fix is on the device, not in TiviMate. For more on how TVs handle picture and sound, CNET TVs has helpful guides.
Fire TV Stick 4K Max
Go to "Settings > Display & Sounds > Audio > AV Sync Tuning". Follow the on-screen test and move the slider until the sound and picture match. You can also set "Surround Sound" to "Stereo" in the same menu to remove decoding delay.
Android TV Box and Xiaomi Mi Box S
Open "Settings > Device Preferences > Sound". Look for the surround sound option and try "Never" or "Stereo" if your soundbar adds delay. Menu names may differ by brand.
Samsung, LG and Apple TV
On Samsung (Tizen) and LG webOS TVs, look in the sound menu for a "lip sync" or "AV sync" option. Also turn off motion smoothing in the picture menu. On Apple TV, open "Settings > Video and Audio > Calibrate > Wireless Audio Sync" if you use wireless speakers.
Soundbars and Receivers
Many soundbars and receivers have their own "lip sync" or "AV delay" setting. Change only one delay setting at a time. If you change the soundbar, the TV and TiviMate all at once, it gets hard to tell which one helped.
Fix Your Network to Stop Sync Drift
A shaky connection can make audio slowly drift away from the picture. Two simple changes help.
- Use Cloudflare DNS (1.1.1.1): DNS is the system that finds stream servers by name. Changing it can help get around slowdowns from your internet provider. Set it in your device's network menu.
- Set a 5,000 ms buffer: in players that use milliseconds, 5,000 ms is a good setting. In TiviMate, choose one of the larger buffer size options.
- Use a cable if you can: a wired connection is usually steadier than Wi-Fi.
When the Problem Is the Stream Itself
Settings can only do so much. If the stream arrives with bad timing, the gap keeps coming back. A steady source makes a big difference.
