i don't want to defend the lamentable state of the ALSA docs, but this
last shot was a bit cheap Fons. the idea behind the ALSA control API was
that equivalent controls on different cards would be controlled in the
same way. sure, OSS provides ioctl (fd,
OSS_THIS_ONE_DOES_MADI_CLOCK_SOURCE, &int) but move that code to any
other device and it breaks entirely. ALSA has its own major points of
API weakness, but this particular one was at least conceived with a
noble goal in mind.

btw, if i was the quality dept, this use of doxygen would not have
passed the "make me happy" test.
