No sound at wit's end. SOLVED

[skizikz]

Hello all,
I have another sound problem.I tossed out my soundblaster cards and went back to onboard.
The box in question has a nvidia MCP61 high definition audio on a Gigabyte M68MT-S2 motherboard.
Her are some hopefully informative results from things I have tried in terminal:

root@localhost ~]# alsactl init
alsactl: init:1743: No soundcards found...
[root@localhost ~]#

 grep sound-slot /etc/modprobe.conf
alias sound-slot-0 snd_hda_intel
alias sound-slot-1 snd_hda_intel


root@localhost ~]# /sbin/chkconfig --list alsa
alsa            0:off   1:off   2:on    3:on    4:on    5:on    6:off   7:off

[root@localhost ~]# /sbin/chkconfig --list sound
sound           0:off   1:off   2:on    3:on    4:on    5:on    6:off   7:off
[root@localhost ~]#




[root@localhost ~]# modprobe snd-snd-hda-intelFATAL: Module snd_snd_hda_intel not found.

the alsaconf does not find any sound card
in PCC the hardware is correctly identified and all seems normal

Hi skizikz,

I had a similar problem a couple months back and I will mention what I did.  At least it is something else to try.

Like you I have a gigabyte motherboard and I am using onboard audio, but it is AMD based, not nvidia.  After a lot of searching, I suggest:

Browse to /etc/modprobe.d/ .  Do you see a file called alsa-base.conf in this location?  If not create it, and add these lines at the end of the file:

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=generic

Then REBOOT and retest sound using headphones and speakers.

After rebooting, make sure all channels are UNMUTED and volume set to 100% in alsamixer.

This worked for me and I hope it helps you.

Is your card turned ON in the 'bios' set up ?
Press Del or F2 or F11 on boot up to get to the Bios settings but be careful what you change !, the should be some setting for the audio.

No such file. Created it with Kwrite and added the above lines.
No luck. Mixers don't start except for Qasmixer which shows no sound card.

I would try removing all alsa related packages through Synaptic.

Then delete
/etc/alsa
/etc/sound/profiles/alsa
/usr/share/alsa

Then reinstall previously removed packages.

Just spotted this...

[root@localhost ~]# modprobe snd-snd-hda-intel

The command is not right. It should be modprobe snd-hda-intel

From terminal type: locate snd-hda-intel to check if the module is there.

What error do you get when trying to start alsamixer?

I have a mini itx box with a gigabyte board. The sound did not work. Issue was no drivers.

Identified exactly what the onboard sound card was, Went to the manufacturers site (realtek?), found the alsa driver rpm, installed and everything worked.

If you have the mobo manual see what the sound card is, do a search on that and if necessary go to the manufacturers site for the drivers.  (or search for the mobo specifications online)

(there is another fiddly, non recommended alternative. Stick to alsa and try to fix with pclinux packages before looking further afield.)

This was after I tried as you suggested regarding uninstall/reinstall of alsa.

This is the error when starting ALSAMIXER:

alsamixer:function snd_ctl_open failed for default:No such file or directory

[agmg]

Can you post a history of the alsa related packages you removed?
Some of them are essential part of the system and should not be removed.
Did you perform a reinstallation of those packages right after uninstalling them?
Did you perform a reboot afterwards?

history from synaptic:

Installed the following packages:
alsa-plugin-equal (0.6-1pclos2012)
alsa-plugins-doc (1.0.25-1pclos2012)
alsa-plugins-pulse-config (1.0.25-1pclos2012)
alsa-utils (1.0.25-1pclos2012)
alsaconf (1.0.25-1pclos2012)
alsamixergui (0.9.0-0.14rc1_5pclos2010)

I reinstalled and rebooted immediately afterwards but it does not seem to have changed anything.

[agmg]

I wonder why you are missing the kernel modules for intel.
An uninstall/reinstall of alsa packages couldn't have removed them, so the problem must be older.

Have you tried a different kernel?
Install 3.2.18-pclos2.pae.bfs from Synaptic and boot from it (select it on GRUB)
First time will take a little longer so be patient.
See if you have sound and perform the modprobe command on the new kernel...

Before that, login as root and check if you have sound from root account.

I am a long way from home so I cannot check this. I think you may need to download the realtek alsa rpm from Taiwan. The names cropping up ring bells, without checking my notes I cannot definitely respond.

My gigabyte mini itx board has a 1.8 atom, #525??? and realtek high def audio drivers. No sound until I installed the rpm driver pack from realtek, then easy.

Your board?
GA-M68MT-S2P (rev. 3.0)
Realtek ALC889 codec <<<<< sounds familiar to me

I am back home in three weeks so could look at my notes then.
(I also sorted it in another but non-recommended way. Stick to alsa.)

2. uname -r?
