I agree with nebajoth, I use now similar settings, previously I had
also some problem with sound on Debian.
It comes from the fact that there is no dependency  dependency from
snd-soc-core to snd-soc-qi-lb60,
if you load sound modules you load snd-soc-core that load
snd-soc-jz4740, but  snd-soc-qi-lb60 is let alone
so you have to have an explicit line for loading it and cannot rely to moddep.

An other problem that I don't understand with sound is the low level
of the mic. It is the same thing on openwrt or Debian and the mic is
hardly usable. Is it a hardware problem or a driver problem. I suppose
you have previously tested the microphone at QI?
