#15927: TINSEL: AUDIO: MidiPlayer::createDriver() assert in DW1 with gm_device=mac
----------------------+----------------------------
Reporter:  dwatteau   |      Owner:  (none)
    Type:  defect     |     Status:  new
Priority:  normal     |  Component:  Engine: Tinsel
 Version:             |   Keywords:  gm_device
    Game:  Discworld  |
----------------------+----------------------------
 With ScummVM 2.9.0 and current Git HEAD.

 It's been reported on the #ios-support Discord channel, with the `dw.gra:
 c8808ccd988d603dd35dff42013ae7fd` Discworld 1 CD/DOS/English release. I
 can also reproduce it on Intel x64 with the similar `dw.gra` CD/DOS/French
 release I have.

 Steps to reproduce:

 * Build with debug support
 * Have `gm_device=mac` set in your ScummVM config
 * Start the game

 The following crash will happen:

 For now, I can't say if the issue is engine-specific, audio-specific or
 iOS/maOS-specific. I'm logging the issue here so that we don't miss it.
