System voice cannot be recorded

[daidi]

I want to distinguish between the microphone and the speaker separately, and I see that there are two different channels with the list interface, but the actual sound recorded with 'include 1,2' is wrong, and it doesn't work properly with 'exclude 1' or 'exclude 2'
