Hi all,

I have a strange problem with alsa and the thinkpad's firmware beeps.
If I use a kernel >= 2.6.30, I can't hear any beeps generated by
thinkpad bios (or thinkpad_acpi module).

I open a bug on alsa's bugtracker, but seems that is ignored:

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4725

I collect some test from other user of Thinkpad mailinglist:

http://mailman.linux-thinkpad.org/pipermail/linux-thinkpad/2009-November/047807.html

And I reported everything on a new thread:

http://mailman.linux-thinkpad.org/pipermail/linux-thinkpad/2009-November/047849.html

and a webpage table:
http://kionez.org/thinkpad_beep/index.php

Today I've play a couple of hour with gentoo's kernel 2.6.32-r1 and the
new alsa-driver (1.0.22.1) without success, if I load anything alsa
related (i.e. snd-hda-intel) the firmware's beeps disappear, even trying
with beep_mode parameter. It works fine until i load alsa.

Is there something that we can do to ear firmware's beeps on new kernels?

thanks in advance


I share your pain. I'm on hda-intel, 2.6.32, and ATIsbx00 (sb600 in my case) with pci.id 1002:4383
Alsa automagically detects an Analog Devices AD1981 (pci.id 11d4:1981) and I have no microphone. I too have entered a bug

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4853

but I don't know if anyone except me has read it. I am trying to change the identification, or even find an explanation of what they try to do. This old box works reasonably well but the alsamixer screen reports


SiS SI7012 
Chip: C-Media Electronics CMI9761A+
View: [Playback] Capture  All     
  

The SiS is right, the C-Media is way off. My problem box reports

ATI  HDA  Intel
Chip: Analog Devices AD1981

and I have no microphone. I lurk here looking for something relevant - but nothing much happens.
