Nessun suono da sound card Realtek alc880 su ubuntu 9.10

Ho assegnato la domanda a Mark Rijckenberg, sono sicuro che con il suo aiuto se ne viene fuori egli risponde solo in inglese ma vediamo cosa accade.

I have assigned this question to Mark Rijckenberg, he answer only in english language but i'm sure he can understand the issue here.

Please execute step 1 in the following procedure (=upgrade to ALSA 1.0.21), then reboot your pc and send us the full terminal output from step 3 and step 4 from this procedure:

https://help.ubuntu.com/community/SoundTroubleshootingProcedure

Thank you for your quite prompt replay. The terminal output from step 3 and step 4 are the followings:

peotta@peotta-desktop:~$

Please send us the contents of the file /tmp/alsa-info.txt.kkS7iIsfEr where your ALSA info is stored.

So send us the output of this command:

cat /tmp/alsa-info.txt.kkS7iIsfEr

Before we proceed, did you first execute step 1 in the following procedure, as I requested before?

https://help.ubuntu.com/community/SoundTroubleshootingProcedure

If you did not, there is no point in proceeding....

peotta@peotta-desktop:~$ cat /tmp/alsa-info.txt.kkS7iIsfEr
cat: /tmp/alsa-info.txt.kkS7iIsfEr: Nessun file o directory

One more time: I have copied the instructions here that you need to follow EXACTLY as described:

Please do NOT skip any steps. Start with step 1. Also keep in mind that you need to upload the ALSA info to Pastebin, so choose Y instead of N. Do not save locally. This is clearly mentioned in the procedure, but was not followed.

The Procedure

In order to gather essential troubleshooting information about your sound card, please follow this procedure:

Step 1

Please try upgrading the ALSA sound system to the newest version, then reboot and retest sound.

If you are using Ubuntu 9.10 (Karmic Koala edition) or older versions, please use this link:

http://monespaceperso.org/blog-en/2009/08/31/upgrade-alsa-1-0-21-on-ubuntu-jaunty-9-04/

Step 2

Open Terminal console to get to the command-line

Step 3

Please make sure you have rebooted your computer at least once. Then proceed with running the following 2 commands - copy&paste (with the mouse) each command onto the Terminal and then hit <enter> after each command.

wget -O alsa-info.sh http://212.20.107.51/alsa-info.sh

bash alsa-info.sh --pastebin

When the alsa-info.sh script asks

"Automatically upload ALSA information to pastebin? [y/N]"

type y and then hit <enter> to make sure the script actually runs and uploads to pastebin. Please post the full terminal output after the script has actually run by creating a new question in launchpad then please copy&paste the terminal output into your newly created question. Carefully inspect the contents of the ALSA Information script at the Pastebin website location that was generated by the previous command

bash alsa-info.sh --pastebin

After upgrading ALSA and rebooting the computer please make sure that the ALSA driver version, library version and utilities version are all exactly the same version number. The file at the Pastebin website location should contain something like this:

# ALSA Version

# Driver version: 1.0.21

# Library version: 1.0.21a

# Utilities version: 1.0.21

If the Driver, Library and Utilities version numbers are not equal then - in most cases - this is caused by one of the following issues:

1. One of the ALSA components was not successfully upgraded during step 1 in this procedure

2. ALSA was correctly installed or upgraded, but a wrong / old kernel was booted instead of the most recent kernel version. In that case, boot the newest kernel version and then retest sound.

For example: if you installed or upgraded to Ubuntu 9.10 (Karmic Koala edition), make sure the running kernel version is 2.6.31-14-generic or higher. Or else sound will not work!

Step 4

Please copy&paste the following command into the Linux Terminal. Please do not copy&paste this command from an email message into the Terminal, as that will only copy part of the command. The command starts with the command cat and ends with the filter snd. So, please copy&paste the entire command below into a Terminal. Press enter. Then type your normal user password when asked, no stars are given as you type. Then press enter again.

cat /proc/asound/cards; sudo aptitude install paman gnome-alsamixer alsa-utils flashplugin-nonfree-extrasound; aplay -l; sudo lshw -C sound; ls -lart /dev/snd; cat /dev/sndstat; lspci -nn; sudo which alsactl; sudo fuser -v /dev/dsp /dev/snd/* ; dpkg -S bin/slmodemd; sudo /etc/init.d/sl-modem-daemon status; lsmod | grep snd

Step 5

Please post results (copy&paste terminal output) here

Sorry for the delay in answering.
Now I've made the full procedure (hoping alla was well done) and I'm posting you the output from step 3:

Hoping you can help me, regards.

Please do the following:

1. copy-paste the following command into the Terminal:

gksudo gedit /etc/modprobe.d/alsa-base.conf

2. In gedit editor, scroll down and REMOVE any lines containing "model=Realtek ALC880 position_fix=0" in the /etc/modprobe.d/alsa-base.conf file

3. In gedit editor, scroll down and REMOVE any lines containing "snd-intel8x0" in the /etc/modprobe.d/alsa-base.conf file

4. reboot

5. After rebooting, resend us the output from step 3 and step 4 from this procedure:

https://help.ubuntu.com/community/SoundTroubleshootingProcedure

There was just one line containing snd-intel8x0 in the /etc/modprobe.d/alsa-base.conf file.

ALSA v1.0.21 seems to be correctly installed, but it is not detecting your sound card at all. So your sound card still does not have any ALSA drivers loaded for it.

This leads me to believe that there might be a bug in the kernel you are running (2.6.31-16-generic #52-Ubuntu SMP) that is preventing it from working correctly with your soundcard.

Please try booting a previous kernel version via the grub boot menu and retest sound.

If that does not help, try booting the Ubuntu 9.04 LiveCD and see if sound works during the LiveCD session.

I booted the previous allowable kernel 2.6.31-15-generic, but with no effect to sound.
With the Ubuntu 9.04 from liveCD the sound was working, even if at low level (the problem I had before).
Finally, what I vave to do? Reinstall the 9.04 version and try to get more sound level with some procedure?

Yes, do a clean install of Ubuntu 9.04.

Then upgrade ALSA to version 1.0.21 using this procedure:
