iMac 5K 2019 Audio

Hi, I am relatively new to Linux and have installed Manjaro Gnome on my iMac 5K 2019, everything I need to work seems to be working great except for internal sound. Bluetooth audio is working fine, but nothing works from my speakers/mic.

Having googled a solution I can see that its been an issue for a number of users but I cant see any recent posts about this.

Does anyone know if there is a workaround/fix to get this working?

Many Thanks

can you provide
