How to maintain the media volume on the Redmi 13C while audio from other source is played?

The built-in Multiple audio sources feature on the Redmi 13C allows the device to not adjust media volume during incoming notifications or while audio from other sources is played. This means some APPs, especially those related to media playback (e.g., music players, video players, streaming APPs or incoming calls, message notifications), can continue playing audio in the background while you use other APPs or perform other tasks on your phone. After enabling this feature, you will enjoy the convenience and have an improved sound effect experience.
To enable Multiple audio sources on your phone, please refer to the following steps:
1. Go to the [Settings] APP on your phone;
2. Select [Sound & vibration];
3. Tap [Additional settings];
4. Turn on [Multiple audio sources].
