Can anyone identify this headphone amp IC?
The markings say AAX IBV or perhaps 1BV. It has 4 pins on each side.

An externally hosted image should be here but it was not working when we last tested it.
You mean that Max chips could be BGA only? Oh no, exactly near a half, or more Maxim headphone amplifier chips has a planar type of package. And according to datasheet MAX97220 has exactly that type of package as on the photo.
P.S. I have the same Bluetoth module, and wondered about that headphone driver too )
