alsa hda-intel not working anymore

[Zenigata]

After the last gutsy update (linux-generic-2.6.22-10), i lost the sound. After a few investigations it occurs that the module hda_intel for my sound card is simply not present. I tried to reinstall most of alsa related packages but it did nothing.

I do not really know what to do, I will try to build alsa and see what's wrong.

my sound card is an ALC861C, and if you need other information just let me know.

Reagrds

Sound problem too with
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)

Recompilation and respecification of the correct options (I never had an installation of alsa that guessed it correctly) in /etc/modprobe.d/sound works

[LEVIS Cyril (atlas95)]

Could you explain how to do?
For me my soundcard has always work correctly....until now...

[Zenigata (drebon)]

I installed alsa-source :

sudo aptitude install alsa-source

then I used module-assistant (that you may have to install too), if you never used it, just do :

sudo module-asistant

then choose "UPDATE", then "PREPARE" and finally select.

In select choose alsa-drivers, then go back, choose to build the selected modules, then wait a little, then choose to install the modules and after that hit escape as many time you need to go back to the console.

Then I do not know with what module do your card work, if it is snd-hda-intel, then there is probably one model that fit better than one other, you can try some models by unloading and reloading the module with "modprobe snd-hda-intel model=XXXX"

where XXXX is the name of the model, normally you should find what model names exist in the docs of alsa-source. (for me it works well with asus-laptop, a few other existing models are "asus" "3-stacks" ans "6-stacks")

if you find a model that fits well to your card, just edit the file "/etc/modprobe.d/sound" to have the following line :

options snd-hda-intel model=XXXX

some people say that one should also put the following :

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

but I do not know if these lines are useful

Thank you for taking the time to report this bug and helping to make Ubuntu better. Do you have the linux-ubuntu-modules-2.6.22-10-generic package installed? Thanks in advance.

[LEVIS Cyril (atlas95)]

Yes I have the modules

[Zenigata (drebon)]

Same thing there, I have that package installed (probably through the linux-generic meta package)

[Brian Murray (brian-murray)]

If you have that package installed snd-hda-intel should be present in /lib/modules/2.6.22-10-generic/ubuntu/media/snd-hda-intel/ . Is it not there?

Well I did not check before recompiling it from alsa-source.

But the alsa mixer did not find any sound device, and when trying to
execute a little script that I used before to fix my micro input
sometimes, I got errors about non existing modules.

here is the script :

/etc/init.d/alsasound stop
rmmod snd_page_alloc
rmmod snd
modprobe snd-hda-intel model=asus-laptop
/etc/init.d/alsa-utils start

maybe it is the two modules snd and snd_page_alloc that do not exists
anymore.

I have this problem also. i have the linux-ubuntu-modules-2.6.22-10-generic package installed and looking in /lib/modules/2.6.22-10-generic/ubuntu/media/snd-hda-intel/ shows there is a snd-hda-intel.ko file.
Doing lsmod | grep snd-hda-intel though returns no results, so the module isnt being loaded.
If i try sudo modprobe snd-hda-intel, it says FATAL: Module snd_hda_intel not found. (notice the difference in hyphens and underscores, is that supposed to happen?)

I am getting the exact same error. rebuilding alsa has not helped.

Kernel treats hyphens and underscores equal for kernel modules. So that it not
an issue.

Just two small questions, did you guys reboot or do a "sudo depmod -a" after building alsa and prior to modprobing snd-hda-intel again?
Are you guys running the kernel you build alsa for?

I did only a reboot and just works :-)
