This provides a complete implementation of kDoAudio through SCI2.1mid, plus partial implementation of SCI3 features. Digital audio calls shunted through kDoSound have also been updated to go through the SCI32 audio mixer, though these shunts are a bit hacky because the ScummVM implementation of kDoSound does not currently match how SSCI kDoSound is designed. It is probably possible in the future to just replace the SCI1.1 audio code (audio.cpp) with the new SCI32 code, since the major differences seem to be that (1) SCI1.1 only supported one digital audio playback channel (this is configurable already), (2) it had extra commands for CD audio playback and queued sample playback.
