The background sound setting for short - video recording may not take effect for several reasons.
Sometimes, the short - video recording application itself may have bugs or glitches. These can prevent the proper functioning of the background sound setting. For example, if the app has not been updated for a long time, it may be incompatible with the current operating system version, causing the background sound function to malfunction.
Solution: Check if there are any available updates for the short - video recording app. If so, update the app to the latest version. This can often fix known bugs and improve the overall performance of the app.
The app may not have the necessary permissions to access the background sound resources on your device. For instance, if the app doesn't have permission to use the microphone or access the audio files stored on your device, the background sound setting won't work.
Solution: Go to your device's settings and check the app's permissions. Make sure that the app has the required permissions, such as microphone access and storage access.
If you are trying to use an audio file as the background sound, the file format may not be supported by the short - video recording app. Some apps only support specific audio formats like MP3, AAC, etc. Additionally, if the audio file is corrupted, it may also cause the background sound setting to fail.
Solution: Convert the audio file to a supported format using a reliable audio converter tool. Also, try using a different audio file to see if the problem persists.
There could be issues with your device's hardware or software configuration. For example, if your device's audio drivers are outdated or there are conflicts with other installed applications, it can affect the background sound setting in the short - video recording app.
Solution: Update your device's operating system and audio drivers to the latest versions. You can also try uninstalling recently installed apps that might be causing conflicts.
