Hello,
Via I2C, I am setting the registers in the TAS5717 (slave) from a LM3S9B96 (master) micro-controller.
These are the values I am setting:
(the first hex number is the register I am writing to, and all the consecutive hex numbers are the values I am writing to that register)

However when I read the registers, I can see all the values that I wrote except for the 5th and 17th value (which both happen to be 0x0F) of registers 0x27 to 0x2B and 0x31 to 0x35. When I read these values, I see "0x03" instead of "0x0F".
Ontop of all this, I am still not getting any output from the TAS5717 Audio Amplifier. Am I missing any registers? Or am I placing the wrong value into a register?
Any help/input would be most appreciated (:
