Microphone and Remote Control of iPod-Headset not working on Macbook


I just installed Fedora on my old Macbook (7.1, Mid 2010). Now I would also like to use my iPod-Headset. The Headphones are working fine, but neither the Microphone nor the Remote Control Buttons. In macOS all is working, so it must be a software issue.

Searching through the internet it seems to be the CTIA-Layout of the Apple Headset instead of https://askubuntu.com/questions/459143/how-to-map-volume-buttons-on-apple-earpods, https://bbs.archlinux.org/viewtopic.php?id=248099. Is there a way to tell Fedora the connector layout?

I would also think about implementing some stuff if required. http://david.carne.ca/shuffle_hax/shuffle_remote.html could be some Help. But where will I get help to start?
