Randy, The CD4016AE is a quad bilateral CMOS switch, and the RC5532N is a dual low-noise op amp. Without knowing how the two ICs are wired, it's difficult to identify the purpose of the device. It is probably an audio amplifier, and the CMOS switch might be used for gain or frequency response adjustment, muting, or possibly input or output selection.
