- * Minimally compliant SunOS compatible audio driver front-end

- * This is a front end for the voxware based drivers that form the standard
- * audio driver system for FreeBSD. It will not operate without the voxware
- * package.
- *
- * This is not a full implementation of the SunOS audio driver, don't
- * expect anything other than vat to operate with it.
