Hi Cameron,

Thanks for sharing your work. For patches to be merged into Ubuntu
kernel, patches need to be backport by sending SRU to ubuntu kernel
team: kernel-team at lists.ubuntu.com with specific format. This allows
reviews from broader audiences.

An example will be like
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938689

 Cover letter: 
https://lists.ubuntu.com/archives/kernel-team/2021-August/122890.html
 Patch: https://lists.ubuntu.com/archives/kernel-team/2021-August/122891.html 

Note: subject's "UBUNTU: SAUCE:" is needed for patches aren't in
mainline kernel, and bug link should be included in both cover letter
and patch description.

Details can be found @

Title:
  No sound on Lenovo laptop models Legion 15IMHG05, Yoga 7 14ITL5, and
  13s Gen2

Status in linux package in Ubuntu:
  New

Bug description:
  All 3 models need the appropriate HDA verbs sent to properly
  initialize the sound hardware.

  Additionally, the Legion 15IMHG05 needs automute disabled otherwise
  speaker output will not return after removing headphones.

  The good news is that I have working patches for all 3.

  However, the 13s Gen2 reportedly has some weirdness on the volume
  control. I don't have this model of laptop so there's not a lot I can
  do. It seems tuning the volume up and down using the keys on the
  keyboard can jump the volume up and down in large increments. Volume
  adjustments via a GUI do not have this issue.
