If there is a conflict, you can turn down the media volume or turn it off so that it will not affect the call volume. I will take my phone Honor 9X as an example to demonstrate the specific steps:

1. Open the phone and find the settings;

2. Enter the settings interface and click Sound and Vibration ;

3. Find the media and call volume settings on the sound settings page. The media volume is music, video, and games;

4. Swipe the call volume to the right to increase the volume. Just slide the media volume to the left to turn it down or turn it off.

This way there will be no conflict.
