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. Regards, Preetam
