Question Displayport after shutdown and boot loses SPEAKER audio

[Xpinux]

Hello I just finished my new pc build and I am experiancing something odd.
When I am with the display port on my monitor after shuting down the pc and power it on again I LOSE completly the sound of external speakers.

When I am using hdmi all is fine. Shut down and power up on again with sound just fine.

HDMI and displayport is connected via gpu.

System is : X570S master
Ryzen 9 5950x
32 gb of crucial ballistix ram from compatability list
MSI rx 5700 XT.
