Input Conditioning Op-Amp
AD8051 is a rail to rail low input current (2uA) Op Amp but uses 10x input bias current than the TL972 and even higher offset current,  so is not well suited to this amplifier  with  unbalanced resistances   1M on (+) and 100K on (-).

This would result in a pop when plugged in from DC offset.

Also the pin numbers are different.

Try to get the right part or use a fine tune range for 2,5V ref if using a 5V supply or V+/2 if not to null the offset , then AC couple the output..
