In my limited experience, it is the capabilities of the sound hardware that
determine
what controls show up in alsamixer.  Here's what lsmod shows on my laptop.
There
is boocoo snd/sound related stuff.  pcspkr is there, too, but doesn't seem
to be referenced by any other driver.  I'm not sure what driver is actually
controlling
the speaker in this case. Not much help, I guess.
