I'm just a little slow sometimess but I think I finally get it.

Both machines in question have on-mobo sound "cards".

Ah. I wouldn't have expected that, surely wouldn't have known it.
I'm pretty clear on the basic concepts of ADC and I'm okay with
plugging in cards but I'm real vague on the wildly heterogeneous
technology that lies between them. :-)

Ah, sooooo. Finally hit on the right hentracks to type. The P3 shows
a "PC Speaker" as one of many "simple controls". The P4 does not. That
means the chips(et) on the P4 just don't got the physical connections
to run/emulate the pc speaker, right?

Okay, I guess I've got it. This box is incapable of beeping unless I
do some arcane hardware hack or modify the source code of everything
that thinks it can send ^G to a/the terminal.
Maybe I can just stick another sound card in it if I can find a vendor
who can actually produce detailed specs before purchase.
Thanks for your help and patience,
