Oh yeah this is AWESOME!!!
this is beautiful but lee mentioned it was available in the sources section,
how do I find alsa-kernel/arm/pxa2xx* and other sources?
I am so happy right nwo I cant standmyself!!!
thank you

You may be interested in an embedded ALSA project I'm working on:-

We currently have support for the SSP, I2S and AC97 interfaces on the
PXA2xx SoC. You will need to use the SSP interface for 24bit audio, as
the AC97 and I2S interfaces only support 16bit samples on the PXA27x.
We don't have your codec (AKM4620A) supported atm, but it's quite
trivial to add new codecs (there are lots of examples). With a few other
minor changes to the ssp driver (adding 24 bit support) you should be
able to start playing/capturing some audio.
