It seems that your codec is not properly initialized. Try hda-analyzer
or other tool to set directly HDA codec widgets and try to find which
widget controls the analog beep (assuming you're using beep_mode=0 in
the latest ALSA driver).

i play a little with hda-analyzer and the last kernel (2.6.33-gentoo),
but i can't get the beep working, if i use a kernel > 2.6.29 every
analog beeps disappears (as reported) and i lose the firmware beeps
(i.e.: when the power chord is detached).

is there's something to know about widgets in HDA codec? i try to see if
there's something beep related in every node, but i can't find anything
useful.

What changed between 2.6.29 and 2.6.30 that could break console and
firmware beep? On some other systems, I did need to switch from pcspkr
module and instead load snd-pcsp. This does not help on the Lenovo X61S
machine. Is there other modules to try?

Have you tried beep_mode=0 with recent drivers? Or disable
SND_HDA_INPUT_BEEP with previous kernels.

I'm not sure if I do things right: I use kernel
2.6.32.9-70.fc12.i686.PAE. Tried putting the following in

The beep_mode option is not in this kernel. You may compile own kernel with CONFIG_SND_HDA_INPUT_BEEP disabled or try to compile latest ALSA snapshot:
