(Android) Audio stops playing randomly on background

When audio is playing on background, it does not prevent the application from eventually being closed by the OS.

When this happens, I do not get any pop up like "unfortunally ... stoped responding".

I have some native apps that play audio on the background, where I never observed this behavior.

I have <preference name="KeepRunning" value="true" /> in the config file, and the following plugins

<plugin name="cordova-plugin-inappbrowser" spec="~1.7.0" />
<plugin name="cordova-plugin-buildinfo" spec="~1.1.0" />
<plugin name="cordova-universal-links-plugin" spec="~1.2.1" />
<plugin name="cordova-plugin-browsertab" spec="~0.2.0" />
<plugin name="cordova-sqlite-storage" spec="~2.0.3" />
<plugin name="cordova-plugin-music-controls" spec="~1.4.1" />
<plugin name="cordova-plugin-x-toast" spec="~2.6.0" />
<plugin name="cordova-plugin-device" spec="~1.1.6" />
