you simply set your "AMD High Definition Audio Device" as standard here (Soundsettings in Windows)

Have in mind that this only works when your soundsystem is plugged into graphic card or on the connected Monitor
PC: R7 2700X @PBO + RX 580 4G (1500MHz/2000MHz CL16) + 32G DDR4-3200CL14 + 144hz 1ms FS P + 75hz 1ms FS
Laptop: R5 2500U @30W + RX 560X (1400MHz/1500MHz) + 16G DDR4-2400CL16 + 120Hz 3ms FS
