Thanks for helping out!

After testing this out and getting really confused about it still not
working I started to look through the early boot output on the serial
console looking for some board revision info. Then I noticed that it
used the sabrelite version of the device tree file since board was
unset in u-boot. By doing a "setenv board nitrogen6x" in u-boot before
booting, which makes it use the correct dtb-file, sound works like a
charm. So I guess it was a user error all along, although a
not-so-obvious one :)

After upgrading u-boot on the board from "U-Boot
2013.01-00058-g5957f6d" to "U-Boot 2014.04" the board variable is set
by default and hence everything works out-of-the-box.

Again, thanks for your patience!

Cheers,
Erik
