Make outputs single ended on CS4234
The device states it can do single ended, which I believe is what I need to achieve stereo sound.


No.  Single ended would just be using AOUT1+ and ignoring AOUT1-, or combining both + and - into a single signal with an op-amp.  For stereo you would use AOUT1 and AOUT2 in either single-ended or differential mode.

Using an op-amp to make a differential output into single ended can be done like this:
