On my Matebook 14 the "old" version of your patch is running without major problems. I even applied your patch to newer kernel versions and it still does it's job ;-) I too really appreciate your efforts!

With pop-os-linux kernel the hardware obviously gets recognized by the new driver but no sound is coming out of neither my speakers nor the headphones. No matter how high I turn the controls...
Anyone else facing this problem? Am I missing something??
