Co-driver calls don't work when I have my sound on my speaker

When I use headphones mr. Mills gives calls while driving, but when I have my sound on my speakers he is just gone, but all the other sound is still there. How is this possible and how do I fix this?

Most likely you need to change to stereo speakers in Windows not 5.1 or 2.1 or whatever.  Phil is on the center speaker channel in those setups.
