[Music Player] Blocks playing music under certain circumstances

Summary

I realised that the music player that is part of the /e/ package does not play music, when I stop playing and resume after a while (i.e. 10 mins). The online thing that helps is restarting entirely the application. The same issue does not appear with other music players (I used Vanilla Player to compare).

Steps to reproduce

• Fresh /e/ installation

• start a song

• stop it/pause

• wait 10 minutes.

• Now the player does not play music anymore.

• I observed this issue on 2 different devices: Mido and Santoni

What is the current behavior?

see above
