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.
