Dell Inspiron 9400 no Sound

[Gomez01]

Hi,

I'm not having any sound on my new laptop Dell Inspiron 9400. I have updated my system using yum and have applied all patches. I'm a newbie in linux so i don't have a clue how to solve this.
I have googled myself to death on this problem but can't seem to find a answer.
First off all the sound card is detected:
lspci

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
i have configured and compiled the alsa sound drivers. using the following command:

./configure with-soundcard hda-intel
make
make install

i have also installed the alsa driver plugins,library,utils
alsa driver version 1.0.11rc5

when i run alsaconf it detects my soundcard as Intel Corporation 82801G(ICH7 Family) High Definition Audio
and it runs ok saying OK, sound driver is configured.

An other thing i found on forums is to enable external amplifiers using AlsaMixer v1.0.11 but i have no such option. I only Have Master,PCM,IEC958,Capture,Input So i have raised all level to max and ensured that they are on. AlsMixer also detects the correct chipset SigmaTel STAC9200.

some more command:
aplay -l

If anybody can help me with this problem it would be nice.
Kind regards
