One other thing to check here is that because the OSS API will iterate
through several different calls to hw_params() since it sets each
parameter individually it's possible that the configuration done in one
of the intermediate states is causing your configuration to spring to
life.  It might be worth looking at what's different about the setup
done by the OSS API and working back from there.
