Missing sound

[HarryBhat]

My friend has a Dell Studio and I recently upgraded it to Jaunty. Since then, I have not been able to get any audio output from any application.
The details of his laptop are as shown-

Also, when I open the volume preferences, I sometimes get the option 'Null Audio Output' (or something like that; I will add the exact words here once I get the error again).
Besides, in sound preferences, if I choose the device as 'HDA Intel STAC92xx Analog (ALSA)' , I get the error message:
'audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Could not open audio device for playback.'

BTW, ever since I upgraded to Jaunty, whenever I try to maximize ANY media player, I am reverted to the login screen.

I have enabled audio for all user groups too.

Could someone tell me what is happening? Was upgrading a BIG mistake?

Do you have your driver??
I have dual booted Vista and Ubuntu and Sound on vista has caused mine to be low try to see If you have muted it on vista because that may be a massive problem.

"I am reverted to the login screen."

I had such strange phenomena with Ubuntu 9.04 too,
when I made noise removal with Audacity.
This problem was, however, solved in some way.
Now I have the "Brown Screen of Death" time after time.

No! Sound is OK in Vista...

Sorry about bumping the thread but I'm desperate for a solution

I have the same sound card, and I'm not getting any audio either...

Audacity works (playback and recording).
VLC works.
Skype works too.

State of sound in Linux not so sorry after all

@ daryl314
Good to know I'm not the only one facing this problem

@ igorzwx,
Will try soon. Thanks

I've got an HP DV4-1435dx, but it looks like it runs the same sound card:

~$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

In order to get it to work, I had to edit the alsa-base.conf file. See post here.
