alsa on Thinkpad T61 no sound

Hi All,

I recently installed the slackware 12.1 on Thinkpad T61 and download the alsa drivers directly from 1.0.16), and compile it from scratch. My sound card is Intel ICH8 Family HD Audio Controller as shown by lspci.

So following the guidance from Alsa site I compile the driver with option --with-cards=hda-intel. The compilation went smooth and after I reboot I got the following lsmod:

Module Size Used by
nls_iso8859_1 3712 2
nls_cp437 5312 2
pcmcia 33688 0
snd_hda_intel 334424 0
snd_pcm 63368 1 snd_hda_intel
button 6096 0
thermal 14620 0
ohci1394 27632 0
processor 27760 2 thermal
yenta_socket 22476 1
snd_timer 17924 1 snd_pcm
battery 6144 0
ac 3200 0
snd_page_alloc 7560 2 snd_hda_intel,snd_pcm
ieee1394 75892 1 ohci1394
snd_hwdep 6596 1 snd_hda_intel
psmouse 35408 0
rsrc_nonstatic 8832 1 yenta_socket
pcmcia_core 33684 3 pcmcia,yenta_socket,rsrc_nonstatic
e1000 115904 0
snd 44068 4 snd_hda_intel,snd_pcm,snd_timer,snd_hwdep
ehci_hcd 40268 0
intel_agp 21140 0
uhci_hcd 30032 0
agpgart 26096 1 intel_agp

so the modules loaded well. However when I tried to play the wav file with aplay I can't hear anything coming out. (Of course I have un mute everything on the alsamixer and max out the volume)

I searched the web for similar problem and found the following guide fronm puppy linux

It basically stated that there are different "models" of hardware for snd-hda-intel and we need to specify the correct models. I know by doing cat /proc/asound/card0/codec#0 that my card is:

Analog Devices AD1984.

So following the directives from that puppy linux site I add the line:

options snd-hda-intel model=AD1984

under "/etc/modprobe.d/sound"
So that file looks like:

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=AD1984

However after I reboot the computer still no sound. Do you guys have any idea of what is missing to cause this problem ?

Thanks in advanced for any help and suggestions

Try with:

options snd-hda-intel model=auto
Btw, why did you compiled ALSA drivers? As far as I know, Intel HDA works just fine. At least it worked for me on older Toshiba and now on Sony notebook.

If the options in the previous post do not work for you, as strange as it sounds, try:

options snd-hda-intel model=Toshiba

options snd-hda-intel model=Acer
Even though this is not your real model, it has work for others having this problem.

Hi All,

Thanks for the answers. It turns out it was a very stupid mistake. I did not to turn on the speaker option on the alsamixer. This was because when I had the speaker turn on it will make a loud beeping sound if I also turn on the Internal Mic. So instead of turning off the Internal Mic I turned off the speaker. And of course no sound came out...

Now it is solved, and from T3slider that AD1984 is not a valid option for snd-hda-intel, and it is supposed to be thinkpad I think, but even if I used the wrong option in the sound file under /etc/modprobe.d my sound card still works anyway. I guess the system just uses the default setup which turns out the same as the thinkpad option.

Thanks again for all your help
