Oh my God, you are right! I got fooled by the "new" string appended to the
name of the codec and I didn't pay much attention to the Makefile, so I
included the wrong codec in my target system. I'm so sorry I made you waste
your time.

Ok thanks!

Ok. Thanks again.

Again, I'm so sorry for making you and the list wasted your time. However,
thanks to this mistake, I've been learning
something about the I2C protocol and the I2C linux framework itself.

I hope that will fix my problem.
