Audio Interface "MOTU M2" works in 1.2.7.1-1 but not in 1.2.7.2-1

Apologies this is my first kernel bug report. If you need more information please let me know and I will do my best.

Operating System:
Arch Linux

Kernel Version:
5.18.11-arch1-1

Basically I have a audio interface (MOTU M2)
https://motu.com/en-us/products/m-series/m2/

It used to work and I updated my alsa version to 1.2.7.2-1 and it has stopped working. Downgrading it back to 1.2.7.1-1 fixes the problem and it appears again.

So TLDR MOTU M2 works in 1.2.7.1-1 but not in 1.2.7.2-1

I am also using pipewire 0.3.54-1 and gnome 42.3 on Xorg with an X86 AMD Ryzen 5950X CPU if that is relevant.

I also made sure to include alsa-info.sh for you :)

Thanks

I incorrectly gave the alsa-info.sh text a description of "MOTU M2 works in 1.2.7.1-1 but not in 1.2.7.2-1" apologies for that.
