[82801H] I have no sound on my laptop inspiron 1420 ubuntu 8.10

I have no sound on my laptop [1], the sound card [2] is detected by the computer without any problem, when you start a song (for instance) this totem starts playing but no sound of any of the speakers or headphones laptop. Try to solve the problem using the workaround of bug 280534 but not get any result, the attached log alsa-info.sh [3].

[1] Dell Inspiron 1420
[2] Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)

I had no sound recently in intrepid. I thought my sound was muted as has happened before so I opened a terminal and run alsamixer, however, it only showed the master volume control instead of all the others that usually exist. I found on ubuntuforums that now to see all the other volume control you need to enter 'alsamixer -Dhw' and sure enough I found that my PCM volume was muted. I may be way off base here but its worth a shot.

unfortunately this is not my problem alsamixer controls are all in 100 (Master, PCM, Front, Sorround, Center, LFE)

I have the same trouble on my dell 1525, also with 82801H soundcard, as I updated to Ubuntu intrepid. I ran alsamixer and there was a loud noise when I turned on the Analog loopback.

On hardy heron I had a similar problem: there was no sound after upgrading modules, but in that case the system didn't recognise the soundcard. I found the solution here:

(on Gaudentius post)
However, now it ain't possible to follow directions, because there is no old modem driver.

I did the following and got sound:

sudo killall pulseaudio
sudo alsa force-reload

 System>Preferences>Sound and change everything to ALSA

Nonetheless, I have to do it every time I turn on the computer.
