Does anyone know why this would be and what I would need to
do to render to the laptop speaker as a ks device.

I realise I could answer by reverse engineering portaudio,
but wondered if anyone could help before I do that.

There's a potential for confusion here, so I want to make sure we're
all on the same page.

When you say "laptop speaker", are you referring to the speaker
connected to the audio hardware on your motherboard? That is, the
one that gets exposed as Realtek Audio or Intel HD Audio or
whatever? If so, then that certainly should be exposed in
ksstudio. You can try graphedt and see if you can attach to it

Or is it possible you mean the primitive two-wire speaker that is
used for boot-time error codes? If that's what you mean, that is
not a KS device, and never will be. If Portaudio supports that
speaker, then it must have its own codec and its own buffer
management. There is no kernel driver to do that.
