sound card

Do you hear the drums at the graphical login screen?
Which sound card do you have?
Can you provide the output of this commands:

sudo lspci
amixer scontrols
amixer sget 'Master'
amixer sget 'PCM'

Thanks

I have tried the above-mentioned commands and with the exception of the command "sudo ispci" command I get positive results. In the case of the sudo command I get "No command found".

I am new ubuntu and linux. I've had no problems except with sound.

I have no sounds at all! NONE

 I will try to be as detailed as possible so whoever is willing to help me will be able to do so.

Soundcard : Sigmatel STAC9200

OS :Linux
Release :Tesesting/unstable
Kernel :2.6.15-27-386
Build time :#1 PREEMPT Fri Dec 8 17:51:56 UTC 2006

Gnome ver :2.14.3 - Ubuntu (2006-07-31)
GCC ver :Uknown
Xorg ver :7.0.0

CPU :Mobile AMD Sempron(tm) Processor 3200+

IDE Interface : nVidia Corporation MCP51 IDE (rev f1)

VGA Controller : nVidia Corporation C51 PCI Express Bridge (rev a2)

Graphic Card : nVidia GeForce Go 6100

Soundcard : Sigmatel STAC9200
------------------------------------------------------------------

I used a program called system info togather most of the previouse information and under the SOUND CARD DETAILS this is what is displayed....

HDA-Intel - HDA NVidia
HDA NVidia at 0xb0000000 irq 225

...Im no expert but I'm thinking it should say something about sigmatel STAC9200 instead of NVidia...???

and under SOUND CARD: It's blank.

-----------------------------------------------------------------

When I go to the taskbar and click System>Preferances>Sound

Down at the bottom It displays : Deafault Sound Card
and in the list it displays: HDA NVidia, and that is my only option. There are not any other chocies in the list.

---------------------------------------------------------------------

This is interesting though....

If I right click on the volume control on in the task bar on the desktop and right click preferances It displays,

Select the device and track to control...
under that I got a list that contains:

HDA NVida (Alsa Mixer)
SigmaTel STAC9200 (OSS Mixer)

It was originally set to HDA NVida (Alsa Mixer) and I changed it to SigmaTel STAC9200 (OSS Mixer) Because that is my sound card. I thought maybe this was all I needed to change...I was wrong.

I still do not have any sound. NONE!

------------------------------------------------------

I have tryed these commands...

sudo lspci
amixer scontrols
amixer sget 'Master'
amixer sget 'PCM'

... and here are there corisponding outputs...
