How to Fix Bluetooth Stuttering / Lag on Aura S4T / Aura S4T Pro?

To further resolve the issue, we recommend the following:

 

1.Connecting the soundbar directly to your mobile phone via Bluetooth for testing playback first.

 

2. Ensure the Bluetooth connection distance is within 5 meters (16 feet) and avoid physical obstructions or interference.

 

3. Try powering off the unit completely, then turn it back on and re-pair the Bluetooth connection.

 

4. If a restart does not resolve the issue, please perform a factory reset on the device.

 

If the problem persists after trying the steps above, we recommend updating to the latest firmware version. Please provide your current firmware version (press and hold the "Source" button on the remote control for 5 seconds.) and the device’s serial number (SN), and contact our customer support team at support@ultimea.com so we can assist with the firmware update.
