I installed Ubuntu 12.10 on my Thinkpad T400 ... but I have no sound and the keyboard buttons for volume up and down do nothing. When I open sound settings, there's nothing: it's all greyed out. It is like the driver is missing.

Alsamixer gives :

card :HDA Intel                              
chip: Conexant CX20561 (Hermosa)

What can I do?

T400:~$ sudo aplay -l

In the upper bar the sound icon is not functionning: enter image description here

The sound works out of the box with a live USB ubuntu with /etc/modprobe.d/alsa-base.conf containing the following:

Driver is ok.

Open alsamixer, make sure your output channels are not muted. Press the left and right arrow keys, to move to different channels and press m to toggle mute / unmute. A "M/M" at the bottom of a column means it's muted

It should look kinda like this:

  • thanks but I checked and they were not muted...still no sound – louis Feb 21 '13 at 20:26

    try: /usr/bin/amixer -c 0 sset "Auto-Mute Mode" Disabled – phipsalabim Feb 21 '13 at 20:39
  • run: gksudo gedit /etc/modprobe.d/alsa-base.conf and add this line options snd-hda-intel model=thinkpad. You will have to reboot. If that doesn't help try resetting your BIOS to factory defaults. – phipsalabim Feb 21 '13 at 21:05
  • I did the auto-mute command and added the line in the alas-base.conf file, still no sound ! I also reset the bios to factory settings ...still nothing, any other ideas? – louis Feb 21 '13 at 23:16
  • Full disclosure: I'm stumbling in the dark. Please try changing the line in the conf file to option snd-hda-intel model=generic, reboot. – phipsalabim Feb 21 '13 at 23:25
  • or possibly: option snd-hda-intel model=thinkpad power_save=0 power_save_controller=N. But it feels like a hardware failure. – phipsalabim Feb 21 '13 at 23:38
  • I guees that you meant "options" instead of "option"....I tried those but still the same.... – louis Feb 22 '13 at 08:42
  • I is not hardware failure because it works out of the box with a live USB ubuntu. – louis Feb 22 '13 at 09:02
  • Try reinstalling everything alsa related libasound alsa-oss etc, or upgrading alsa. I'm out of ideas. Sorry. – phipsalabim Feb 22 '13 at 10:55
  • I just reinstalled everything alsa related...no I have sound, but I stille can't control it (the icon is not functional in the upper right corner) – louis Feb 22 '13 at 12:14
  • you have sound now? That's awesome. Try: sudo apt-get install --reinstall indicator-sound, then killall unity-panel-service. Do your sound control keys work? You might have to restart pulseaudio: pulseaudio -k – phipsalabim Feb 22 '13 at 12:29
  • yes I have sound now . But I have strange errors on $ pulseaudio -k E: [pulseaudio] core-util.c: Failed to create secure directory: Permission not granted E: [pulseaudio] main.c: Impossible to kill the daemon  : Permission not granted – louis Feb 22 '13 at 18:15
  • sudo apt-get install --reinstall pulseaudio – phipsalabim Feb 22 '13 at 18:18
  • Hi....my /home was mounted from a separate partition, and this partition was ntfs, so there was permissions problems...Now I formatted this partition to ext4....and the sound works! – louis Feb 22 '13 at 20:47
