Hello, i need help, got macbook pro with no sound at all, found missing coil and soldered in.

Now it plays chime sound, but when OS booted press volume control buttons there is no sound.

Deeply clean the audio connector.
Use cotton stick, like the ones for ear cleaning.
YouTube has some related videos...

Just remove R6805 and be happy.
