disable_dgpu option breaks sound

[hacker1024]

I have a Dell Inspiron 7586 with Realtek ALC3254 audio, an integrated UHD 620 iGPU and an NVIDIA GeForce MX150 dGPU.
When I add the disable_dgpu option, no audio input or output devices are detected, and no sound cards show up in /sys/class/sound.

This is something which has not been tested yet, could you attach a dmesg ? (I don't have a device with a dgpu)

I also added a kernel command line parameter "remove_dgpu" which takes the value of the port of the pci device to remove i.e. "remove_dgpu=04:00.0", could you try it and see if you have the same sound issue ?
