Are you using gumdroid?  - That is what I am using. I have a directory gumdroid/hardware/alsa_sound .. And this is where I believe libaudio.so is compiled.

In your BoardConfig.mk in gumdroid/device/gumstix/overo/ you should have the following:
BOARD_USES_ALSA_AUDIO := true

Maybe concentrate on fixing the compile error first -- I am new to all of this - but what is the error you get?
I did a 'mm' in the gumdroid/hardware/alsa_sound and it seemed to compile correctly (except the files generated where alsa.default.so instead of alsa.overo.so - so must be missing something from a make file/setup higher up).

While looking into your error, I noticed I also have the file /system/lib/hw/alsa.overo.so  - did you copy this file from the pre-built image as well? I believe it is required for /system/lib/libaudio.so. Also I believe /system/lib/libaudiopolicy.so is required to be copied.

Hope this helps,


Ben
