I will make a long story short.
If you have recently upgraded your PC with Ryzen CPU and motherboard ( especially X570, B550 chipset) and get unstable screen flicking, headset disconnection issue. Try this solution.
-Get into your BIOS setup menu upon boot.
-Find PCIEx option to change from PCIE Gen4 to PCIE Gen3.
-Problem resolved. ( Tested with Pimax 8KX on B550 chipset and HP Riverb g2 on X570 chipset )
