Hi,
In this case, it's not a Windows problem, but rather a driver issue with the headset, which isn't 24-bit or 20-bit. I tried finding the driver on the website, but there's no download link.
If possible, you could do the following: the motherboard driver is usually Realtek, and the headset's USB-C driver is different, which is why it doesn't have a channel.
Could you check if the box has a QR code with the headset driver?
Thanks
