Audio error in 0.57.devXX.

[Pucksnok]

Hello.
Just installed a fresh computer with Windows 11 and Python 3,11 and tried the latest dev version. PATH is correct so shouldn't be the issue. I have tried to install Python both as user and for everyone, (PATH manually cleared between and reboot done).

mpf 0.57.0.dev31
mpf-mc 0.57.0.dev10
mpf-monitor 0.57.0.dev3

I checked out b460101#top and I'm not sure if this is the same issue or not.

Error...

Can add that I also tried with mc_demo downloaded from latest dev, same error.

This is a bit of a different error I think, because if the audio fails to import I think it will print that friendly message in the logs? There might be more information in these previous issues: #450 #436

I don't have a Windows machine so I'm not able to test. (And I don't know Cython either, which is what the audio system is written in, so apart from me getting it to build without errors, I don't know what else to do?)

So I think we're back to needing to find someone who knows Cython and Python and has Windows who can dig into this?

This is in my MC-log.

Ah, ok so that is the same error as those other issues. I still have no idea how to fix it, but at least it makes sense now.
