Hello Philipp.
I have the same Yoga 14IAP7 with no subwoofers sound.
I'm using Ubuntu 22.04.

I downloaded the vanilla 5.18 kernel ando could apply your patch, compile and install the kernel.

I still have no sound in my subwoofers, but the alsa-info output changed.

Do I have to blacklist any module or anything?
I haven't made any change in that regard.
My system is still loading the default intel sof drivers.

Could you provide a short list of steps?

Regards,

Gervasio
