It's quite possible that your laptop doesn't have the
"PC speaker functionality".

Traditionally, the PC speaker was completely independant
from any sound cards. It even was present when no sound
card did exist. Early laptops also included such a speaker.

More modern laptops then included a sound card and the
speaker (three speakers internally), but quicky the
PC speaker got removed, and access to its functionality
is provided through the sound card, offering a kind of
"PC speaker API".

And maybe this "PC speaker API" isn't present on your
laptop anymore.

Does dmesg show any "speaker" lines, such as this?

	speaker0: <PC speaker> port 0x61 on acpi0

And even if it is shown this way, it doesn't imply that
the "PC speaker API" of the sound card is handling the
corresponding calls.

Finally, and maybe you've already checked it, what is
the mixser setting for the PC speaker channel of the
sound card, if it does exist?
