I have a relatively new Dell Inspiron 1525 laptop which for the first few weeks ran without issue. I installed or upgraded something and now the sound won't work.

I have spent many hours combing through similar posts, but to no avail, including these:
http://linux.dell.com/wiki/index.php...4#Known_Issues
http://linux.dell.com/wiki/index.php...Kernel_Upgrade

I have also tried reinstalling every ALSA and GStreamer related package using the Package Manager.

I'm relatively new to Linux but do have a minor clue. However, I need instructions for how to diagnose the problem as well as specific things to try. Here's what I know:

On a command line if I hit the backspace key I get a system beep - good stuff.

When I hit the volume control on the top panel, the first time I get:

The volume control did not find any elements and/or devices to control. This means either that you don't have the right GStreamer plugins installed, or that you don't have a sound card configured.

The second time I get:

No volume control Gstreamer plugins and/or devices found.

#uname -a
Linux ninegy-ninegy 2.6.24-23-generic #1 SMP Mon Jan 26 00:13:11 UTC 2009 i686 GNU/Linux

#speaker-test
speaker-test 1.0.15

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

ALSA lib conf.c:3985:(snd_config_expand) Evaluate error: No such file or directory

etc.

Any help is greatly appreciated...
