For some strange reason, lspci does not display my sound device and I am having troubles getting sound to work on my Linux installation.

My systems specs ...
Slackware 10.0, kernel 2.6.7
Fujitsu S2020A laptop, AMD 1900+ XP-M, Radeon IGP 320M, Sigmatel STAC 9767 audio

There seems to be no sound device of any type!

In addition, I have done google searches regarding this "Sigmaltel STAC 9767" sound card, those who have got it working and probed it claim that is actually an "ALi M5451 PCI AC-Link Controller Audio Device"

I have tried recompiling the kernel with the module as well as built in, but the result is always the same in dmesg ... "No soundcards found". Please help!

is the card actually pci? are you certain the card is in working condition? is isapnp enabled in your kernel? have you tried a pnpdump?
good luck.

Thanks for the reply PEACEDOG!

I'm not sure if the card uses the PCI bus, but I know that is an onboard chip. I am running Microsoft Virtual PC, and the sound is working in Windows.

pnpdump displayed 2 things ... "Sound Blaster 16" and "Game Port". Fujitsu labels my notebook sound device as "Sigmatel Audio STAC 9767 codec", so I'm guessing "Sound Blaster 16" is inaccurate.

Can you please try to boot with following options:
pci=bios nolapic acpi=off
Make sure apic is enabled (so there isn't a noapic option)
Check /etc/lilo.conf if you are using lilo
or
/boot/grub/grub.conf (in some versions /boot/grub/menu.lst) if you are using grub

Also: What kernel version are you using ?
What displays
uname -r

It lloks like an interrupt problem.

Thanks for the reply Vlad-A!

My kernel version is 2.6.7

I have tried editing lilo.conf to add the following lines

pci=bios nolapic acpi=off

But when I run lilo, I get the following message:

Unrecognized token "pci" at or above line 14 in file `/etc/lilo.conf`

Hi,

where did you add the boot options ?

It shall be in the "append" row of the section for your 2.6.7 kernel


.....
image = /boot/vmlinuz-2.6.7
......
append = "pci=bios acpi=off nolapic"
.......

.........

Be aware that there will problems if you have multiple append lines within one kernel section.
It's better to put all boot options for a certain kernel image withen one append.

Here how it looks in my lilo.conf. /sbin/lilo did not report any errors after adding the above
options.

.....
image=/boot/vmlinuz-2.6.7-mm6
label="linux_2.6.7-mm6"
root=/dev/hdb10
initrd=/boot/initrd-2.6.7-mm6.img
append="pci=bios devfs=mount acpi=off nolapic resume=/dev/hdb8 splash=silent"
vga=794
read-only
......

Vlad-A, I got the boot options to work. However, when I perform lspci, nothing shows up. pnpdump displays the same information as before. As well, during bootup it still displays "No soundcard found".

after running pnpdump
what is displayed when you run:

lsmod|grep sb

Thanks for helping me out Vlad-A!

Hmmmmm... :-)))

Do you have enabled ISA and ISA PnP support when you compiled your kernel ?
CONFIG_ISA
CONFIG_ISAPNP
and also
CONFIG_PNPBIOS

How were those settings in your .conf file whne you compiled the kernel ?

What is the setting of "PnP OS" in your BIOS ? If you enable it, then the BIOS does *not* configure the PnP devices,
but relies on the Operating System.

What is the contens of your /etc/isapnp.conf file ?

Thanks again Vlad-A!

I compiled my 2.6.7 kernel to have ISA support. I'm not too sure about ISA PnP, so I did the following ...

Using "make menuconfig" I saved my kernel configuration to a file, then I used pico to open the file and searched for the values

CONFIG_ISA=y

That's all good, but when I tried searching for the others, pico reported ...

"CONFIG_ISAPNP" not found
"CONFIG_PNPBIOS" not found

So I cut down the words ...

"ISAPNP" not found
"PNPBIOS" not found

Apparently, the values aren't even there for me to change.

So I decided to add them in instead, like the following ...

CONFIG_ISA=y
CONFIG_ISAPNP=y
CONFIG_PNPBIOS=y

Saved the configuration, and recompiled the kernel. However, when I rebooted, I still go the same message "no soundcards found" so then I decided to do a "alsaconf" to see if alsa could probe my sound device given the new kernel settings. Unfortunately, alsaconf couldn't probe anything.

Those entries seemed uneffective, shall I remove them?

As for BIOS settings, my laptop has VERY few options. I was unable to find a "PnP OS" or "Plug an Play OS" option in my BIOS. The only uncommon setting I found was ...

ACPI Aware OS [Yes]


I don't have a isapnp.conf file, but there is a isa.conf.sample file. Here are the contents of my isapnp.conf.sample file ...

# LD n = Logical device, ie write to reg 7
# IO n = IO descriptor n
# BASE n = IO/Mem address
# INT n = Interrupt req n
# IRQ n = Interrupt level

Well, since we do not know if your BIOS is PnP able or not,
you can disable CONFIG_PNPBIOS.

However your sound card *IS* PnP able, otherwise pnpdump would not find it.
Therefore CONFIG_ISA=y, CONFIG_ISAPNP=y shall reamain as they are.
However in order to configure the card isapnp needs informations which are
stored in /etc/isapnp.conf.

You can generate the /etc/isapnp.conf from the pnpdump output. Be aware that
you need to uncoment the config. statements since they all have a # in front of them.
take a closer look on the pnpdump to see what to uncoment.

Check also:
man pnpdum
man isapnp
man isapnp.conf

I wonder if you can configure your card manualy.

I am not 100% sure, but it could be somethig like

modprobe snd-sb16 isapnp=0 io=0x0220 irq=5 dma=1 dma16=5

Perhaps you need also to add mpu_port=-1
