[solved] Alsa driver Problem

GLS064 · Last edited by GLS064 on Sun Dec 04, 2005 12:30 pm; edited 1 time in total

Good Morning or good evening ;-)

I have to soundcards im my computer. Soundblaster Live ( emu10k1 ) and an onboard sound chip ( via82xx ). I followed the instruction from this Page and I have this problem when I boot my kernel :

"Error inserting snd-seq-device ( lib/modules/kernel-2.6.14.3/ ... ) unknown symbol in modul"
"Error inserting snd-emu10k1 ( lib/modules/kernel-2.6.14.3/ ... ) unknown symbol in modul"
"Error inserting snd-emu10k1-synth ( lib/modules/kernel-2.6.14.3/ ... ) unknown symbol in modul"
"Error inserting snd-mixer-oss ( lib/modules/kernel-2.6.14.3/ ... ) unknown symbol in modul"
...

and

the file

/dev/sound/dsp doesn't exist on my computer.

try upgrading the kernel or alsa packages. also make sure you compile them as modules in the kernel config.

if you compiled your own kernel make sure you compiled the modules for it too. I do:
# make && make modules_install

I believe /dev/sound/dsp is for oss.

do this to see if your sound card is detected:
# lspci | grep audio
or
# lspci

Make sure /usr/src/linux is pointing to the correct kernel.

You can also delete /lib/modules/kernel-2.6.14.3 then reinstall the modules with this:

well, I tried this already. usr/src/linux/ point to the right kernel source. I also tried alsa from the project homepage.

When I run alsasound there is something strange. I have ( as I told ) only to sound cards ( Sound blaster Live and Via AC 97 onboard ). But alsaconf shows me 3 cards:

-emu10k1
-via82xx

and

- legacy device ( ISA chip ).

I have made a screenshot

http://www.people.freenet.de/bvthadden/alsaconf.jpg

But the mainboard ( KT4V from MSI ) does nont have any ISA Slots anymore.
Alsaconf tries to configure a sound card snd-*** always

Upgrading kernel ? To 2.6.15-rc4 ? I already use the latest Kernel Version ( stable ) from kernel.org.

Ok, now you needn't worry about that ISA option in alsaconf. That shows up for me too. I guess ISA cards do not support plug and play so they cannot be autodetected. That's why there is an extra option to probe for ISA cards.

That snd_*** thing is a nasty bug in alsaconf (that doesn't seem to get fixed ever).

You have to edit the file /etc/modules.d/alsa yourself and replace the snd_*** entries with valid entries.

For example I think for the soundblaster live it should look like this:

Did you ever mess around with the alsa-driver package?
Please post the exact error when you modprobe the module. (No ... on the end, that part is important)

checklist:
-do you have udev or devfs?
-is the kernel properly configured (normaly you can retrive the config from /proc/config.gz)
-are the modules ok (lsmod)
-have you choosen the right install method (the last time i installed alsa there were 2 methods: one for the modules and one when it was compiled inside the kernel)
-right settings...
-non interferences with others sound systems such as lirc or esd but here /dev/dsp should be avaliable
-mabe(i don't know well /dev) make a simlink of the real dsp file that is into dev to /dev/dsp

the /dev/ directory is where devices files are stored
udev and devfs are manadging it (creating theses devices file)
devfs is a kernel "module"(i don't know how else you can call kernel part)
udev is a userspace program
udev is beter and devfs is deprecated

mount -t devfs none /dev
try this and try it also in fstab
->then look after /dev/dsp

if it devfs was mounted at startup try the oposite (remove it)

GLS064, try this:

i found that the snd-*** problem was fixed sometimes and not others. and i am having trouble with the 1.0.10 modules all of a sudden. i finally figured out that if i do a /etc/init.d/alsasound stop and then made sure all modules were unloaded, _then_ did alsaconf, it works. ymmv

if the problem is solved please put [solved] after the title of the thread.

I've got an onboard sound chip. This is what just worked for me:
- recompiled the kernel with alsa as modules
- emerged alsa-driver
- modules-update
- alsaconf

Anyhow this thread helped me, cause I was a bit confused about this issue before

Yes, that's what I wanted to say

Trying to mount devfs is rather pointless because usually if it's not mounted it meanst you are using udev.

You shouldn't add thing manually to the mtab (I think) because these shows filesystems that are currently mounted and should be update automatically.

Headrush's tip seems to make a lot more sense. :wink:

GLS064 · Posted: Sun Dec 04, 2005 4:51 am Post subject:

ok, devfs doesn't exist om my system

GLS064 · Posted: Sun Dec 04, 2005 4:57 am Post subject:

ah, I found this :

Headrush · Posted: Sun Dec 04, 2005 11:22 am Post subject:

GLS064, did you try what I said?
And if so, what are the exact errors now? (There is no way the error can be the same if you did what I said)

Ok, I finally got it to run. But don't ask me, please. I think, something was really mixed up. Again, thanks a lot for the help :wink:
