The Hyperx Cloud alphas. I take it they are not correct!!!Install the Realtek Audio Drivers from the motherboard support page.
Which DTS device (heaphones/ speakers) do you have?
Straight from the ASUS product page for my Mobo:Correct me if I am wrong, but I do not see anywhere in the specifications the feature DTS.
The Hyperx Cloud alphas.
I have the cloud Alpha 2. No USB sound card came with them.Assuming you mean HyperX Cloud Alpha S.
It connects via the 4 pole 3.5mm connector to consoles and laptops. And via USB to desktops. Desktops use a 3 pole 3.5mm connector for sound out + a separate 3.5mm for sound in (mic). You use USB as sound device, not a Realtek device.
