Fix DTK audio not working after loading a savestate

Browse Source 
The main problem was that the volume of the mixer wasn't savestated.
The volume is typically 0 at the beginning of a game, so loading a
savestate at the beginning of a game would lead to silent DTK audio.

I also added savestating to StreamADPCM.cpp.
