Bug description:
[Impact]
When the machine is docked with an external monitor, it is able to output
display, but the HDMI/DP audio output option is lost in DGFF Hybrid
Discrete/Discrete mode(Nvidia GPU).
[Fix]
Nvidia provides a patch to fix it
https://patchwork.kernel.org/project/alsa-devel/patch/[email protected]/
in 6.4-rc3
dc4f2ccaeddd ALSA: hda: Add NVIDIA codec IDs a3 through a7 to patch table
[Test]
Verified on the target machine.
{Where problems could occur]
The patch just adds IDs, and won't lead to any regression.
