No sound after minimizing Cubase 8 and maximizing MuseScore back

I have MuseScore and Cubase opened simultaneously. When I minimize MuseScore and go to Cubase to do something there, then minimize Cubase and go back to MuseScore, sound stops working. There's no sound on playback, or when I'm clicking on the notes. Only restarting MuseScore helps, but it's pretty uncomfortable to do this when I'm switching back and forth between both applications constantly. I do have the "Release Driver when Application is in Background" option in the Device Setup menu active, so when I minimize Cubase, all the other applications play sounds normally. So it appears to be a problem with MuseScore only.

I'm using MuseScore version 2.1.0, revision 871c81e, Windows 7 64 bit, and Cubase LE AI Elements 8 64 bit.

Is there any way to fix that?
