I'm having a bit of a problem. Currently I have a headset which connects into a mixamp and has 2 inputs, 3.5mm aux and a USB cable. The USB cable plugs into my PC which powers the mixamp and the 3.5mm cable plugs into my PS4 controller. However, when I want to put my PC into sleep mode it cuts power to the mixamp causing my headset to not function. Is there a way to provide power in sleep mode?
