Hi,

You need to provide more information.

First, the output for lspci
Second, the output for cat /etc/modprobe.conf
The output for cat /proc/asound/card0/codec#* | grep Codec would also help.

Code:

/proc/asound/cards reads "--no soundcards--" without quotes

and finally i think this info regarding alsa drivers installed at a standard installation of f7 might help :

Code:

alsa-lib-1.0.14-0.4.rc3.fc7
alsa-utils-1.0.14-0.5.rc2.fc7

hope i have posted sufficient information required.. waiting for ur replies..
thnx..

That's plenty of information, thank you for providing it.

OK, so your sound card may be among the models that ALSA recognizes, but not properly. There are different possible solutions but you can start with the simple ones first and maybe you'll by lucky.

First the important part here is the following line in /etc/modprobe.conf:

Quote:

options snd-hda-intel index=0

For some people, editing this line by specifying a model did the trick. For example:

Quote:

options snd-hda-intel index=0 model=3stack

And then reboot

There are other possibilities such as model=6stack or model=auto or model=laptop, etc... That's why I asked you for the output of cat /proc/asound/card0/codec#* | grep Codec. Knowing which codec you have would help to know which model specifications are more likely to work. Are you sure that you can't get that information?

However, there are chances that simply modifying modprobe.conf won't work. In that case you will have to upgrade ALSA to the latest version (1.0.15).

rs_vijay · 11-11-2007, 07:17 AM

again i should thank u for ur reply sir..

yes sir.. there is no /proc/asound/card0 , instead the file /proc/asound/cards has the line

Code:

--no sound cards--

i have tried those model=... by adding it to my /etc/modprobe.conf followed by a reboot and none of those worked..

i tried upgrading to alsa-1.0.15.. but in the configuring step i found that i don't have the kernel sources for kernel 2.6.21 which i'm currently using i.e /lib/modules/2.6.21/build points to a location that doesn't exist.. i don't understand why kernel sources aren't installed at a standard installation of a linux distro (fedora-7 in my case !!) ..

is there any way to get the kernel sources of my currently configured and working kernel other than recompiling the source for 2.6.21 available on the net ??? i mean something like getting that from my installation dvd etc..

hope i'm sufficiently clear..
thnx and regards..

Iltbreg · 11-11-2007, 11:21 AM

Right, so your sound card is not being recognized at all. I should have seen that from your lspci output, there's no audio device specified. Sorry.

Well, it appears that upgrading ALSA to 1.0.15 would be the thing to do. I myself had tried it back when I had Fedora 7 on my laptop. I compiled everything from source and I failed miserably. So the thing I did was to replace Fedora 7 with Fedora 8. It's easier and F8 has the latest drivers, in addition of having improved laptop support in general over F7.

So if there is something that I can suggest to you is to install Fedora 8, if you don't mind doing that of course.

Iltbreg · 11-11-2007, 11:44 AM

No no no no no! Forget the first part in my last post!! There is an audio device detected in lspci!! Sorry, sorry , sorry... What was I thinking?

It's right there:

Code:

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

One thing that you can do is run alsaconf.

But there are chances that the sound still won't be working after that. In that case, an ALSA upgrade would be necessary. This bug with that kind of sound card has been widely reported to the alsa-devlopment team and they fixed it in their latest version. In that case, my suggestion to go with Fedora 8 still stands.

Again, sorry for the previous post.

solve my problem ... here is some related output...

the above one seems a little bit improvement... earlier it read no sound cards !!!

hope this might be sufficient information ... awaiting ur reply..
thnx.. and regards

Iltbreg · 11-12-2007, 12:01 PM

That's plenty of information, thanks.

OK, first, I must say that I didn't expect your modprobe.conf to look like this. I expected it to be like the one you had with Fedora 7. That snd-usb-audio thing looks wierd to me. So here's what you will do.

First make a backup copy of your current modprobe.conf file.

Once this is done, you will edit modprobe.conf and do the following:

1) Comment out the two last lines like this:

Code:

# alias snd-card-7 snd-usb-audio
# options snd-usb-audio index=7

2) Add the following lines at the end:

Code:

alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0

Just make sure that there is a carriage return (blank line) at the bottom of the file.

3) Reboot

It is however possible that even after all this, you still have no sound. In that case, you may need to specify a model. If you need to do that, try the following:

Code:

options snd-hda-intel index=0 model=thinkpad

or

Code:

options snd-hda-intel index=0 model=lenovo

or

Code:

options snd-hda-intel index=0 model=auto

Good luck.

harsha101087 · 11-28-2007, 09:41 PM

Srry sir for not replying u...thanks for giving the guidance...
ihave done wat u have told me..but it didnt work..still no sound..so

I have performed again clean install..of fc-8 and also tried installing ubuntu 7.10..still the problem of sound remains.. now plz find the following information...

cat /etc/modprobe.conf

Code:

alias eth0 tg3
alias scsi_hostadapter libata
alias scsi_hostadapter1 ata_piix
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0

waiting for ur reply..

Iltbreg · 11-29-2007, 08:11 PM

So you're saying that after a clean install, even if you specify a model in modprobe.conf, as suggested above, the sound still isn't working?

If you go to that link http://www.mjmwired.net/kernel/Docum...ration.txt#757 you will find (starting at line 757) a list of other model names that you can try, according to different codec chips (ALC262 in your case but you can try the others too).

If even after all that you still get no sound, then I afraid your problem is beyond me. The only thing that I could suggest in that case is that you file a bug report at the Alsa Project web page (https://bugtrack.alsa-project.org/alsa-bug/). They could probably propose you other solutions like a Realteck patch to install for alsa driver, or something like that.

harsha101087 · 12-10-2007, 08:25 AM

Hi Sir....
I am really grateful to you..for trying to solve my problem..of sound in my laptop....
and finally i have found the solution for my problem..
The soluiton is like this.... edit the etc/modprobe.conf like this...

options snd-hda-intel index=0 model=fujitsu...

and this really worked....but the input output jack like earphones..headphones..etc dont work....
if you can try to solve this...problem...i would be really grateful...

Thanking you..
harsha

MHansel · 01-15-2008, 03:08 PM

Modifying the /etc/modprobe.conf file and adding "model=fujitsu" at the end worked like a champ. Thank you all for your help!

I got the similar problem with ALC861, alsaconf can figure out my card and alsamixer -c 2 works, but have no Master or PCM, and left, right, or center can't change the volume.

I'll try this in my /etc/modprobe.conf:

Quote:

alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0 model=3stack

See more options or alsa configurate guide:
