sound not working: AC'97

Googly · 02-18-2004, 09:30 PM

I know this has been asked before but I can't figure out how to get my sound working.

I have some sort of on board AC'97 sound thingy
It worked automagically when I used redhat 9.0

I'm using debian 3r2 with kernel 2.4.18-bf2.4
sndconfig detects it as: Intel Corp. l82801BA/BAM AC'97 Audio
and doesn't complain at all but I can't hear anything.

the system beep works and comes out of the speaker

when I plug in a mic and cat /dev/dsp the pattern changes when I make noise in it (and the font gets wierd whee!!)

I'm gonna go try alsa again
KTHXBYE!

I downloaded the newest version of alsa and compiled everything ok but when I ran alsaconf it said:
Running update-modules...
depmod: *** Unresolved symbols in /ib/modules/2.4.18-bf2.4/kernel/sound/pci/snd-intel8x0.o
Loading driver...
Setting default volumes...
Saving the mixer setup used for this in /etc/asound.state.
/usr/sbin/alsactl: save_state:1061: No soundcards found...

could this be caused by compiling with the wrong kernel source (my graphics card complained about unresolved symbols and that was the problem)?

KTHXBYE

What mainboard you on? I'm having a helva time myself trying to get my ECS SIS 735 ac 97 codec to work.
It shows up as three different drivers for the same thing, intel, ali, and oss.

You might want to drop by my posting Sound problems, a gent has some insight as to what you need to do to correct the problem.

Thanks.

i agree you should tell us what motherboard do you use. we must know what type of chipset do you have. for purpose i have VIA chipset. i've compiled it in kernel as a module and inserted it. there are 2 modules i have to insert in order to make my sound card work:

via82cxxx_audio and ac97_codec (i don't even need alsa)

also be sure that you have privileges to use /dev/dsp (because many problems with sound are caused by that

).

Googly · 02-19-2004, 09:17 PM

after chmod'ing /dev/dsp all my programs stopped complaining about there being no sound card, but there's still no sound.

my computer manufacturer's web-site says the chipset is:
Intel 845 Chipset

psoh: where is your sound problem post? I can't seem to find it

thanks for all the help, I'm gonna go try some more stuff.

EDIT: in /etc/modules.conf it says:

Code:

### update-modules: start processing /etc/modutils/sndconfig
alias sound-slot-0 i810_audio
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :

### update-modules: end processing /etc/modutils/sndconfig

but I have no /bin/aumix-minimal could that be a problem?

I still think Unresolved symbols in /ib/modules/2.4.18-bf2.4/kernel/sound/pci/snd-intel8x0.o might be a problen

typing insmod -p snd-intel8x0 outputs:

EDIT: someone suggested modprobe to fix unresolved symbols so I typed
modprobe snd-intel8x0
and it said unresolved symbol change_page_attr, and trying to modprobe that said it couldn't locate it!
any idea on what change_page_attr is or how I can fix this?

jogurt666 · 02-20-2004, 12:23 PM

i'm almost sure that i've found a solution. kernel 2.4 supports Intel i8xx sound cards. try compiling this as a module:

Sound -> Intel ICH i8xx...

i dunno how should the module be called but try looking for it in /lib/modules/2.4.xx/kernel/drivers/sound. just insert it, and your sound card should now work fine. let me know if i helped you.

Googly · 02-20-2004, 08:03 PM

how would I compile Sound -> Intel ICH i8xx as a kernel module?

I looked in /lib/modules/2.4.xx/kernel/drivers/sound and the relevant looking things were ac97.o ac97_codec.o and i810_audio.o
ac97_codec and i810_audio were already loaded
and I loaded ac97 but there's still no sound

also I tried cat /dev/dsp and it said it was busy! should that be busy all the time?

rberry88 · 02-20-2004, 08:09 PM

I have a ASUS A7N8X Deluxe motherboard that has the onboard nforce2 for sound. I use the AC97_codec and I8xx sound modules in the kernel. If you re-compile your kernel you will see a selection for the Intel I8xx and nforce boards module selection. You can select to either include it in the kernel or build as a module. If you haven't done this then that would be where you would start.

Googly, I think my problem is I don't have root capabilities. I can't change the /etc/modules.conf for a correct driver, I've gone thru the Mandrake control panel thus am stuck. I can use the terminal just fine, but when it comes to administering fixes I'm denied. A gent said I'll have to go into Kde to in the control panel or something to allow the root as a user. Being a novice user sucks sometimes...

My sound card is onboard SIS 735 Ac 97 codec, picks up three drivers which I don't need, and are not compatible. I think the driver should be something like snd-intel8x0 which is supposed to be default but I'm going to have to change that with the new ALSA driver. Hopefully I won't get as frustrated with figuring out how in the heck I can do root changes...
