I dont know how to check the alsa-utils version. Its part of android 
gingerbread source tree.
There is also an ambiguousness as to whether its a problem with 
hw_params or sw_params function.
Is there any way I can use something as simple as ctags with vim in 
android source tree?

Is there any updated documentation for starters in alsa soc for the new 
pandaboard 2.6.35 kernel?
I want to learn and master, but I am only getting information in bits 
and pieces.
