Test failures on Python 3.12

Fedora has just finished rebuilding all its Python packages with Python 3.12. mpd2 has some tests failing in the build at the moment:

I see a deprecation of get_event_loop(), but I'm not clear what's causing this test fail:

https://docs.python.org/3.12/library/asyncio-eventloop.html#asyncio.get_event_loop

Any ideas?

Hello,

Any thoughts here? (I see CI also failing for Py3.12.)

Cheers

[Mic92]

Sorry. This project doesn't have a high priority, since I stopped using mpd years ago. I would totally merge PRs though.

[sanjayankur31]

Sure, no worries. Not urgent here either.

It may be an idea to set up a team of maintainers who can look after the project perhaps? I see lots of folks use it, and lots have contributed already too.

[Mic92]

That would be great, as you can see from github profile, I already have enough repositories otherwise. Happy to move this repository also to a new home.

Fixed in #222
