Comment (by eriktorbjorn):

 This isn't a Mac music player issue, as far as I understand. It's just a
 sound effect that gets passed on to Sound::playSound(), where it's played
 as one of these:

 {{{
         else if ((_vm->_game.platform == Common::kPlatformMacintosh) &&
 (_vm->_game.id == GID_INDY3) && READ_BE_UINT16(ptr + 8) == 0x1C) {
                 // Sound format as used in Indy3 EGA Mac.
                 // It seems to be closely related to the Amiga format, see
 player_v3a.cpp
                 // The following is known:
                 // offset 0, 16 LE: total size
                 // offset 2-7: ?
                 // offset 8, 16BE: offset to sound data (0x1C = 28 ->
 header size 28?)
                 // offset 10-11: ? another offset, maybe related to
 looping?
                 // offset 12, 16BE: size of sound data
                 // offset 14-15: ? often the same as 12-13: maybe loop
 size/end?
                 // offset 16-19: ? all 0?
                 // offset 20, 16BE: rate divisor
                 // offset 22-23: ? often identical to the rate divisior?
 (but not in sound 8, which loops)
                 // offset 24, byte (?): volume
                 // offset 25: ? same as volume -- maybe left vs. right
 channel?
                 // offset 26: ?  if != 0: stop current sound?
                 // offset 27: ?  loopcount? 0xff == -1 for infinite?
 }}}
