Hi,

seems that with new ALSA version ( starting frm kernel 2.6.30) we loose
the beep functionality on our thinkpads. Probably, as Henrique de Moraes
Holschuh write in this ML, is related to "ALSA switching the HDA
mixer+codec to "digital beeps" or whatever, which is incompatible with
the signal path used by the firmware." [1]

I would like to collect some test in order to report them to alsa-devel
mailing list.

So, make sure that:

- you have an hda-itel soundcard (according to thinkwiki these chips are
 installed into R/T/X/Z 60 [2] and R/T/X/Z 61 [3] )
- the laptop is running on AC power (and not on battery power)
- thinkpad-acpi is correctly loaded into kernel
- alsa mixer and volumes are set correctly (i.e.: Beep is not mute)

then, the first test:

Try to generate simply three beeps with thinkpad-acpi:

# echo 2 > /proc/acpi/ibm/beep

as root, or with sudo

$ sudo sh -c 'echo 2 > /proc/acpi/ibm/beep'

and now the second one:

Try to detach power chord, in order to produce the two firmware beeps
that notify the switch from powerline to battery.

Please report here the results of two test ( do you ear beeps? :P ) ,
the distribution you're using and kernel version ( $ uname -a ).

Many thanks for collaboration :)

k.
