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:/
in 6.4-rc3

[Test]
Verified on the target machine.
{Where problems could occur]
The patch just adds IDs, and won't lead to any regression.
