If you're experiencing sound interruptions or cutoffs on the Xiaomi TV Box S (2nd Gen), please refer to the following troubleshooting steps:
Scenario 1:
If the issue occurs when you are using the built-in speaker of your TV, please refer to the following methods:
1. If it is playing audio content from an online source, please ensure that your internet connection is active and stable;
2. Check if the sound interruptions occur across different contents or channels. This can help determine whether the issue is specific to a particular source;
3. Check the sound settings by navigating to [Settings] >> [Display & Sound] >> [Advanced sound settings] >> select [Select Formats] and [AC4 dialog enhancer] >> check the relevant settings;

4. Turn the Xiaomi TV Box S (2nd Gen) off and unplug it from the power source. Wait for a minute, then plug it back in and turn it on;
5. If possible, connect the Xiaomi TV Box S (2nd Gen) to another TV to see if the issue persists. This can help determine whether the problem is with the Xiaomi TV Box S (2nd Gen) or the TV;
6. You can check for system updates by going to [Settings] >> [System] >> [About] >> [System update]. If it is the latest version, a message will appear on the screen indicating that your system is up to date;
7. As a last resort, you can try performing a factory reset by going to [Settings] >> [System] >> [About] >> [Reset]. Please note that the operation will erase all the data, so be sure to back up important information before proceeding.
Scenario 2: 
If the issue occurs when you are using an external device like a soundbar, please refer to the following methods:
1. Make sure the device is functioning correctly. Try disconnecting it to see if the built-in TV speakers exhibit the same sound issues;
2. Verify the audio source is connected properly to the TV. Ensure that the cables are not physically damaged and they are securely plugged into the correct input ports;
3. Make sure the external device has the latest firmware or software updates installed;
4. If you are using a Bluetooth speaker, make sure the distance between the speaker and the TV is within a reasonable range, and there are no obvious objects or sources of signal interference in between.
If the above troubleshooting methods can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
