 Saving the volume to the DB on each volume change is unnecessary.
 To optimize DB usage, the patch saves the volume only on exit of the TV
 Player (TV::PrepareToExitPlayer).

 There was also a small bug:
 On each volume change in the TV Player the volume is saved twice when
 software volume is configured:

 In libs/libmyth/audio/volumebase.cpp VolumeBase::SetCurrentVolume
 - Calls UpdateVolume, which calls SetSWVolume, when software volume is
 configured it saves
 - the save in SetCurrentVolume itself
