Hi Gareth,
The schematic looks okay to me. You should verify the basics with the customer for more information:
1. Is the device correctly powered. Can you confirm that the appropriate pins are 1.8V and 3.3V?
2. Is there valid I2S data being supplied to the device? What frequencies are they using for the SCK, LRCK, BCK?
3. If the clocks are valid, the charge pump should be working. You would see approximately -3.3V on the VNEG pin.
Thanks,
Paul
