Question AMD RX570 audio problem.

[Zoomvet]

Hi, I've just built my new PC. This is the first time I use an AMD GPU. I usually open podcasts in Firefox and listen to them while playing games. I have noticed a problem that when I open the game or alt-tabing, the sound will be mute untill the game finish loading up (takes about 2~3 seconds). I'm still using Windows 7 64 bits. How do I fix this?
