New description:
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 audio-specific or iOS/maOS-specific.

Comment:
I'm moving this to the AUDIO component, because it doesn't only happen
with the Discworld games. I can also reproduce the error with DOTT for
example, where it will lead to `ERROR: IMuse initialization - Cannot
connect` with `gm_device=mac`.
Also, regarding Discworld, it's also possible to reproduce this with the
`dw-demo-cd` demo.
I also tested if the new https://github.com/scummvm/scummvm/pull/6682 PR
could have fixed it, but the problem is still there on an up-to-date tree.
