Try the following steps:
Make sure your headset is connected to the correct ports on your computer. It should be plugged into the PC’s discrete graphics card and a USB 3.0 port. Here's how to identify the correct ports:
USB 3.0 ports have a special logo with an "SS" mark (indicating "SuperSpeed"). The port's inside piece is normally blue, but older USB 2.0 ports are typically black or white on the inside.
If your computer has two HDMI ports, use the one that connects to the graphics card, not the computer's motherboard. It's not always obvious, which is which, though discrete ports are often located in an expansion slot on the computer. If you try one port and it doesn't work, try the other.
Go to the headset manufacturer’s website and update the drivers and firmware for your headset.
