      Description

      After upgrading from 5.11.1 to 5.11.2 Android crashes when trying to play a sound. Here is the code:

       

          if(!player) {
              player = new QMediaPlayer(this);
              player->setVolume(100);
              QMediaPlaylist *playList = new QMediaPlaylist(player);
              playList->setPlaybackMode(QMediaPlaylist::Loop);
              playList->addMedia(QUrl::fromLocalFile(tempDir + "/horn.mp3"));
              player->setPlaylist(playList);
              player->setMuted(false);
          }
          if(player->state() != QMediaPlayer::PlayingState)
              player->play();
      

       

      I am getting plenty of messages in the console before it crashes

      And so on a hundred of times then it calls it a day and crashes.

      Tested on 2 devices (Android 7 and Android 5).

      I downgraded to 5.11.1 and everything is working again.
