 The iMuse engine of Indy4 seems to have troubles, at least when using
 MT-32 (I didn't yet test other sound options).

 I first noticed the problem due to the lost dialogue and the cutscene
 where Sophia reads it in the office, since after closing the book, the
 music started again from the beginning. I then noticed that while in the
 original interpreter reading the book anywhere else is not supposed to
 influence music at all, in ScummVM it seems to confuse iMuse when opening
 and closing the book, which I especially noticed in the dig site after
 turning on the light. It results in terruptions in the music or the music
 jumping back several seconds.

 I checked further and there were numerous instances where the fades
 between music tracks didn't work (for example, the travel music just cuts
 off instead of fading out, when you visit Iceland or Monte Carlo in team
 mode for the first time).

 I honestly don't know if it is an iMuse problem or an MT-32 problem, but
 the music behavior is not correct compared to the original.

 EDIT: After using other music options, where the problems remain (though a
 bit less noticable), it indeed seems to be an iMuse problem.
