I don't care about API compatibility -- as long as oss lets you do the
same stuff (possibly by making different calls) I think it's a good
replacement.  The deprecation warning for linuxaudiodev doesn't mean
it's illegal to use it today -- it means it will go away in the future.

Typically, we don't remove tests for deprecated code until we remove
the deprecated code itself.  This saves us from accidentally breaking
the deprecated code before it's time to kill it.
