Sorry to warm up another old topic, but as you can see im a total n00b to Linux, and i've read the other topics about sound and i'm not a bit wiser now...

I have an INTEL AC97 Onboard Sound Chip, if i do lspci then this is the output:

I downloaded ALSA and followed the instructions (can't post the URL of the Instruction, but it's for intel8x0 on ALSA-Project Website), but i doesn't work for me...

When i do the modprobe snd-intel8x0 , then i get this ERRORS:

If i then type dmesg then this is the output:

As i already stated above, i'm a total n00b and i have no idea what that means and what i can do about it, the Problem i have is that i want to run GNOME and GNOME doesn't start without sound-driver installed, it always says something like "Esound couldn't start: /dev/dsp not found" or something like that...


I would really appreciate it if you could help me!
Thanks!

You're lucky, as I had the exact same problem and fixed it only two days ago. Although my sound card was different, yet I'm using kernel 2.6.4. Here are some guidelines. Make sure you're installing alsa 1.0.4. I tried 1.0.1, 1.0.3 but neither worked. Also, make sure that when you do ./configure for the drivers, the modules are installed in the correct directory. You can explicitly specify a directory with ./configure --with-moddir=/lib/modules/2.6.4. See if this helps you any.

When i make
./configure --with-cards=intel8x0 --with-moddir=/lib/modules/2.6.4/
then the configure is working, but at make i get an error:

In file included from /home/flo/alsa/alsa-driver-1.0.4rc2/acore/sound_oss.c:2:
/home/flo/alsa/alsa-driver-1.0.4rc2/alsa-kernel/core/sound_oss.c:27:2: #error "Enable the OSS soundcore multiplexer (CONFIG_SOUND) in the kernel."

make[1]: *** [/home/flo/alsa/alsa-driver-1.0.4rc2/kbuild] Error 2

make: *** [compile] Error 2


what does that mean to me?

Hi,

for those of you (as me before solving) getting this error of unresolved / unknown symbols in the future I paste the email of Jaroslav Kysela, the author of the intel 8x0 module who kindly replied me:

It seems like that snd-page-alloc module was not inserted or it is old.
Try 'rmmod snd-page-alloc' and 'insmod snd-page-alloc'.

I tried as he told me and it works like a charm !!!!!!!!!!!!!!!!!!!

i know that i probably won't be very helpful since i'm pretty new to all this but i was having problems with my sound too all i did in kde was go to kmix then to configure mixer. now everything works but i use slackware current hopefully that helps. if not i jump in my books for another less simple method

something else people might want to do in terminal is alsaconf for some that could be the fix they're looking for.
