DESCRIPTION
These drivers provide interfaces for various kinds of PC audio cards.
Some of these drivers are unsupported. Some of them are known to have
problems. See the BSD/OS release notes for details.
Audio services are provided through a generic audio layer that abstracts
various device specific details into a single API.
This API is the same one used by the Linux kernel and 4-front technolo-
gies. An excellent overview of the API can be found at http://www.4front-
tech.com/pguide/index.html (note that the interface described in the
above link is slightly different (newer) than the API included in
BSD/OS).
