** Description changed:

- This bug is for tracking purpose.
+ BugLink: https://bugs.launchpad.net/bugs/2051050
+ 
+ Currently this patch is in the linux-next, and will be in the
+ mainline kernel v6.8-rc2, there is no need to SRU this patch to Noble
+ kernel, Noble kernel will have this patch automatically.
+ 
+ [Impact]
+ In the gnome audio setting, if we adjust balancing setting, it doesn't
+ work at all on a Dell machine with cirrus codec, that is because with
+ the current driver, the exported amixer controls can't be handled by
+ pulseaudio.
+ 
+ [Fix]
+ Cherry-pick a mainline kernel patch, this could fix this issue.
+ 
+ [Test]
+ Booted with the patched kernel, move the bar to the left or right to
+ adjust the balance, we could hear the sound from left channel or right
+ channel accordingly.
+ 
+ [Where problems could occur]
+ This change will not create "Master Volume" amixer controls, probably
+ will make the audio control malfunction, that is we couldn't control
+ playback or capture volume correctly, but this regression possibility
+ is very low, we already tested the patch on the machines with cirrus
+ codec, they all worked well as before.

  Currently this patch is in the linux-next, and will be in the
  mainline kernel v6.8-rc2, there is no need to SRU this patch to Noble
  kernel, Noble kernel will have this patch automatically.

  [Impact]
  In the gnome audio setting, if we adjust balancing setting, it doesn't
  work at all on a Dell machine with cirrus codec, that is because with
  the current driver, the exported amixer controls can't be handled by
  pulseaudio.

  [Fix]
  Cherry-pick a mainline kernel patch, this could fix this issue.

  [Test]
  Booted with the patched kernel, move the bar to the left or right to
  adjust the balance, we could hear the sound from left channel or right
  channel accordingly.

  [Where problems could occur]
  This change will not create "Master Volume" amixer controls, probably
  will make the audio control malfunction, that is we couldn't control
  playback or capture volume correctly, but this regression possibility
  is very low, we already tested the patch on the machines with cirrus
  codec, they all worked well as before.
