| It seems like you have the correct driver built into your kernel, HDA_INTEL. Are your channels unmuted? You can verify by running alsamixer, and making sure the volume is turned up for things like Master, PCM, etc., and making sure there isn't a MM under the bar, signifying that the channel is muted. |

Hi.. Yes, all my channels are unmuted, I check it out with the alsamixer, before I post it here, and now that you mentioned I checked it again.
But this "MM under the bar", I don't know what that means. Sorry.
Thanks for answering.
Best,

In alsamixer when a channel is muted it shows an MM under the bar for the channel... if it's unmuted it shows a OO.
Are you sure every channel is unmuted? (In practice you don't need to unmute all channels, but it helps when debugging.)
If all the channels are unmuted, could it be that you have more than one sound card in the system? In alsamixer you can press F6 to select the default sound card and see if there are any other cards listed.
Also, is your user in the audio group? |

Yes, the user is in audio group.
And yes, I'm sure every channel is unmuted. I pressed F6 and choose the hda intel device, but didn't work.
If will help, I can post a printscreen of alsamixer.
Thanks,
Best,

Sure that would work...
Can you also post the output of?
Also try grepping dmesg for 'sound' and 'audio', just to make sure it isn't reporting anything. |

The printscreen is here: https://picasaweb.google.com/lh/photo/FZSJJvuz1OG1KU_y1x4Q0A?feat=directlink
The another informations that you ask for:
| Quote: | # dmesg |grep -i hda
[ 1.907247] HDA Intel 0000:00:1b.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[ 1.908230] HDA Intel 0000:00:1b.0: setting latency timer to 64
[ 2.279909] #0: HDA Intel at 0xdfdfc000 irq 16
# dmesg |grep -i sound
[ 0.950962] Advanced Linux Sound Architecture Driver Version 1.0.24.
# dmesg |grep -i audio |
This last one, didn't show anything.
Some more information:
| Quote: |
# cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xdfdfc000 irq 16
# cat /proc/asound/devices
1: : sequencer
2: [ 0- 1]: digital audio playback
3: [ 0- 0]: digital audio playback
4: [ 0- 0]: digital audio capture
5: [ 0- 0]: hardware dependent
6: [ 0] : control
33: : timer |
Best,

| What happens when you unmute the Front and Headphones channels? (Note the MM above each of the channel names.) |

Sorry, but how can I unmuted the Front and Headphones channels ?
It doesn't answer to the up commando on the keyboard.

Select the channel with the right/left arrow keys, and press m to unmute/mute. The volume of the channel is independent of it being muted or unmuted -- meaning an muted channel can still have 100% volume. Some channels as you can see have no volume control, but can be muted/unmuted. This is the case of Headphones and Front for you. |

Just to make sure we are looking at the right direction, would you load up a live CD, such Ubuntu, and check whether the sound works there?
