TODO: The code in this method is very complicated and convuluted. Maybe we
can improve it.
First off, one needs to understand why it is so complex. It tries to honor
the user's music_driver config, but with the restrictions imposed by midiFlags.
Hence it must either select a suitable default driver (for example if
musicDriver is set to MD_AUTO), or it must try to fall back to a suitable
driver resp. the NULL driver.
Different games support different output drivers, as indicated by midiFlags.
Some of the occuring combinations are:
- TOWNS games always want towns or null
- some scumm games allow only pcspk, pcjr
- some scumm games allow pcspk, pcjr, adlib, MIDI
- some games allow adlib, MIDI
- some games only allow MIDI
- did I miss something?
My hope is that we can simplify the whole selection process by iterating over
the list of available drivers and looking at their "flags" member.
