I didn't get how you integrated ALSA along with Android source but, here is
the way to go.
1. You need to have the following entries in your .repo/local_manifest.xml
file under android source directory.
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="platform/hardware/alsa_sound"
path="hardware/alsa_sound"/>
<project name="platform/external/alsa-lib" path="external/alsa-lib"/>
<project name="platform/external/alsa-utils"
path="external/alsa-utils"/>
</manifest>
2. Run 'repo sync' in android source directory.
You are recommended to do it on a fresh android source tree (not
customized).

We should be taught not to wait for inspiration to start a thing. Action
always generates inspiration. Inspiration seldom generates action.
