Low level control of system speaker in Windows

Question

Is there a way to take complete control of the motherboard speaker in Windows? So, instead of calling a function like this:

beep(durationMs, frequency);

I can use:

beepContinuous(frequency);

So all I have to specify is a frequency and it will output the correct voltage to play that frequency.

There's a good discussion of a bunch of audio API choices on this SO question. The most basic technique is to use the waveOut calls in the Waveform Audio API set.
