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/20230517090736.15088-1-nmah...@nvidia.com/
[Test]
Verified on the target machine.
{Where problems could occur]
The patch just adds IDs, and won't lead to any regression.
