Problem with 82801G Intel CH7 Audio (ALSA)
 

Hello everybody,

My name is jose from mexico and I'm a kind of newbie, and i just installed slackware 12. I configured the X's server thanks to a guide and i also configured my network and somethings to my work (designer and programmer)

But when I was trying to configure my audio I had a problem with, I have an Integred Audio (82801G Intel CH7 High Definition Audio) the alsaconf detected with a Sigmatel driver (or something like that). I ran the audacious and it shows me like it was playing my mp3 files but when I turn the volume up of my speakers these didn't work properly I mean they didn't do anything not even a simple beep! or something.

I got a guide from a guy explaining the "solution" but in Ubuntu and I had to recompile the alsa with a driver but nothing happened and now I dont even detect my audio card with alsaconf...
I downloaded the last version of the alsa-driver, alsa-utils, alsa-tools.

Isn't it ironic? :S

Please if someone can help me.. please do it, step by step :P 'cause i don't know much 'bout it.

=)

Thank you.

I have the same problem with this sound card in suse 10.3
I try every possible solution but it still do not work
Suse 10.3 knew it ich7 and use snd-intel as driver
kmix is full open but still no sound

so I wiil follow you,re problem to
If I find a solution I will let you know

all the best

Can you post the output of 'lsmod' and '/sbin/lspci -vv'.

Also, I know you probably already did this but check 'alsamixer' and make sure the volume is not muted, just to be extra sure.

Solution! How to Configure 82801G Intel Audio
 

Hello again...

You know, special thanks to a guy in freenode who helped me with this problem, nick 'el_choya_II' a real guru.

Well first step:
I unistall all packages about alsa, alsa-utils, alsa-oss and alsa-lib.

Second step:
Reinstall all packages (I recommend you that install all packages with your manager i.e. apt-get, slapt-get, etc)

Third Step: (as root)
# cd /usr/src/linux
# su
# make xconfig
And you'll see a graphic tree of the kernel configuration, you have to go to Sound -> Advanced Linux Sound Architecture and you have to see if it's marked with a point or a (*) like that.

Fourth Step:
Now we have to go to PCI Devices -> Intel HD Audio, we have to see if Intel HD Audio is as module a dot on xconfig and on menuconfig is M.

Fifth Step:
Now try as root:
# modprobe snd
# modprobe snd-hda-intel

Sixth Step:
If everything is ok without error up to this moment then we have to add those lines in /etc/rc.d/rc.modules and save the changes with pico or vi

Seventh Step:
Then, now ...
# alsaconf
(remember.. install alsa-utils hehe 'cause you'll need it to do this).
and:
# alsamixer

and voilá! you'll get audio.. :) try with audacious or with amp..

thank you I did that and it worked for me :)

So, in other words, the solution is the same for all the other Intel HDA sound problems (whose number is legion): Upgrade to a newer kernel which contains newer versions of the ALSA drivers.

I had your same problem and i solved it by deleting the last row of /etc/modprobe.d/sound and adding this one:

new problem
 

hehe now i have a new problem, when i turn on the computer i have to type alsaconf and alsamixer again, why?

Because you forgot to run 'alsactl store' as root to store the volume levels and other settings it generated.

Add to your /etc/rc.d/rc.modules this row:

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
no sound :-/
