I don't see anything wrong with your setup, however I think you need to
create the devices by running the snddevices script found in the
ALSA-driver at the project's official page. I had similar troubles, I'd
recommend you installing the driver, the library and the utilities (to
have alsamixer, depends on alsalib). Hope this info is useful.
