Hi ferdi
suggest to look at sabrelite board with sgtl5000:
linux-2.6-imx.git - Freescale i.MX Linux Tree
as for voltages, check ER1
http://cache.freescale.com/files/analog/doc/errata/SGTL5000ER.pdf
for probe error: check i2c signals with oscilloscope, also one can add printfs
to probe fuction.
Best regards
