No sound with Sennheiser U320 Gaming headset

Hi everyone,

When the system boots I don't get any sound on the headset. Re-plugging it into a different or the same USB sometimes works. I've noticed that every time I plug it in there's 2 lines that make reference to a keyboard, which seems odd. After that, there's a bunch of "cannot gets and sets" for a frequency.

Any help would be highly appreciated. I'm willing to apply any patches you deem necessary so we can get to the bottom of this problem.

journalctl --system output:

I'm willing to change or add code to make this work, if anyone has any past experience in supporting devices like this it would be fantastic to have some concrete pointers. Thank you!
