	I must be missing that module. Is this the module
referred to in the sound/Kconfig file in the kernel source? It says:

	I recently installed beep on 4 Dell systems. Each uses a
2.6.5 kernel I built since each system has a CD berner and ALSA.
All of that works properly.

	If one tells the P.C. to beep at 3 KHZ for 10 seconds,
the system does pause for ten seconds but there is no sound from
the small speaker.

	I know from programming in assembler in DOS that the
speaker has a timer/counter IC driving it and you can either
send a tone or a steady DC signal depending upon which bits in
the timer control registers you set or clear.

	I don't recall seeing any modules in the kernel that
mentioned the P.C. speaker which is why I am asking the
question.

	When I installed beep, I did set the suid bit to root
because each of the systems in question has a serial console and
that is what the man page recommends one do in that case.

	There are no errors or complaints, but no beeps either.

	The systems do beep during booting and grub beeps. After
that, there is never another sound from the timer counter system
until the next reboot.
