ADAU1787 can't output sound and can't detect sound input using line in.

I cannot get any sound to come out of the headphones. I have used a beep generator on all of the outputs but I cannot hear anything. I have a pair of headphones connected to the stereo out. I have the line in connected to the PC's sound output.

I used the level detector on the inputs but I cannot get any levels detected.

I have changed the register to be headphone mode.

I can hear sound coming out of the headohones when I turn on bypass switch S7.

I have turned on Fast and Slow DSPs. I'm not sure what else I should change.
