how can i increase sound in circuit Opic and opa alice

It sounds like you don't have any preamp at all. That thing you showed only uses USB to supply phantom power; it doesn't amplify anything.

This is probably the cheapest thing that will do what you're trying to do:

1642's fine, i'm sure. Especially if it's not a fake one...
