Hi all,

I am not sure I can make this problem clear, so I upload the screenshot below.

I click the loudspeaker icon, and there are two mixers. I can hear the sound if I click the lest one. The right one is gray and cant click. I dont know if this is normal, I just know I have never had this problem before. I found this problem because I found the sound of music is noisy, so I checked the loudspeaker icon. How do you think about the two mixer?
