Ubuntu not producing any sound

Asked by Arnault

I am running Hardy Heron on an Intel core2duo Toshiba laptop (Satellite P100-403). The audio card is Conexant HD audio and it does not produce any sound at all (everything else works fantastically well). I read several posts about this specific problem but none of them, including reinstalling Alsa drivers, really worked for me.

The sound is working fine with Windows XP, and I checked the mixer is not muted. Here are some data :

1. lspci | grep Audio output :
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

2. Kernel version : 2.6.24-19-generic

3. aplay -l output
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: CONEXANT Analog [CONEXANT Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: Conexant Digital [Conexant Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

4. grep Codec /proc/asound/card0/codec#* output
Codec: Conexant CX20551 (Waikiki)

5. lsmod | grep snd output :
snd_hda_intel 344728 3
snd_pcm 78596 1 snd_hda_intel
snd_timer 24836 1 snd_pcm
snd_page_alloc 11400 2 snd_hda_intel,snd_pcm
snd_hwdep 10500 1 snd_hda_intel
snd 56996 10 snd_hda_intel,snd_pcm,snd_timer,snd_hwdep
soundcore 8800 1 snd

Any help appreciated

I have toshiba p100-106 with the same sound card. it works fine on me.
this problem was solved on version 7.10

this is my output.
aris@Kubuntu:~$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

in the mixer, try to choose HDA intel for sound.
if it not this, i don't know what it is..

Thanks for this. We have the same lspci output and I already selected HDA intel for sound in the mixer, so it does not come from this. But it gives some hope it should work with the right setup

I would suggest that you reinstall your linux with a new carefully processed media.
for me it works out of the box

did you try to boot with acpi=off?

First i suggest you to be sure your system is fully upgraded, to check:
open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get clean all
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean all
sudo apt-get autoremove

and reboot your pc type:

sudo reboot

give your user password when requested, you don't see nothing when you type it, then press enter.

Then...

Open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo asoundconf list
sudo asoundconf set-default-card <name of card>

give your user password when requested, you don't see nothing when you type it, then press enter.

Hope this helps

hi I just installed Ubuntu 8.10
I have the same problem (no sound) on the same hardware.
lspci | grep Audio >>
Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

aplay -l >>

Earlier i was using Windows XP and every thing was fine.

I read several articles regarding this.
Went over https://help.ubuntu.com/community/SoundTroubleshooting step by step
nothing seems to work.

Does anyone has a fix/work around?

Hey. Finally i have sound ! :)
adding 'options snd-hda-intel model=auto' fixed the issue

Can you help with this problem?
