[Interest] Setting the Volume of QMediaPlayer conflict

[Jason Kretzer]

Ah, found this.  https://codereview.qt-project.org/#/c/79918/  Unfortunately, I am not familiar with what branch is associated to what version for Qt.  This says it has been merged into the stable branch.  However, I assume that it has not made it into 5.3.1 yet as the problem does persist — unless I am incorrectly coding the below.

So, I set each volume accordingly, the first player to 1 and the second player to 95.  However, they both end up playing at the same volume (95).  If I remove the second player, the first player will play at a low level as it is supposed to.  Adding the in the second block however adjusts both.  The two qdebug statements at the end contradict what happens though as it shows that each volume is set appropriately, though if you listen it is obviously not the case.  Is there a trick that I am missing?  Thanks!
