This bug is awaiting verification that the linux-nvidia-
tegra/6.8.0-1001.1 kernel in -proposed solves the problem. Please test
the kernel and update this bug with the results. If the problem is
solved, change the tag 'verification-needed-noble-linux-nvidia-tegra' to
'verification-done-noble-linux-nvidia-tegra'. If the problem still
exists, change the tag 'verification-needed-noble-linux-nvidia-tegra' to
'verification-failed-noble-linux-nvidia-tegra'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
  [Impact]
  HDMI/DP audio isn't working on Dell's USB-C dock.

  [Fix]
  Leave Maud/Naud as is, since the hardware programmed the right value
  already.

  [Test]
  HDMI/DP audio always comes out from the USB-C dock after the fix is
  applied.

  [Where problems could occur]
  The commits affects _all_ HDMI/DP audio that connects to Intel GFX. So
  all of them are affected hence the regression risk isn't low.

  Therefore let the commit sits in OEM kernel first. Stable kernels can
  pull in this fix after it's getting thoroughly tested.
