no sound in ubuntu 10.04

Steps that helped when nothing else worked:

1. Get ALSA Update Script from here: http://ubuntuforums.org/showthread.php?p=6589810
2. Unpack and Launch it:
2.1 Input command
"sudo ./AlsaUpgrade-1.0.22.1-2.sh -d"
in Terminal and press "Enter"
2.2 Input command
"sudo ./AlsaUpgrade-1.0.22.1-2.sh -c"
 in Terminal and press "Enter"
2.3 Input command
"sudo ./AlsaUpgrade-1.0.22.1-2.sh -i"
in Terminal and press "Enter"
3. Restart Computer.

If after restart you still find you have no sound, simply input this command in Terminal:
"sudo alsa force-reload"

;)

Also, as mentioned before, this thread ( http://ubuntuforums.org/showthread.php?p=6589810 ) contains FAQ to problems.
FAQ #112: “Sound Problems”.

Hi,
I followed all the steps upto sudo alsa force-reload and rebooted the system too. But still no sound.
What next to be done. Please help

Hmmm....

You also should check if you have installed this package:
linux-backports-modules-alsa-xxxxx(1)-generic-xxx(2)

,where:
xxxxx(1) is the kernel version you currently is latest installed and used;
xxx(2) is "-pae". Install "generic-pae" if your installed kernels name contains "generic-pae" or "generic", if your kernels name contains " generic";

if it does not help, please fill new bug report in launchpad and collect debugging log as described here:
https://wiki.ubuntu.com/PulseAudio/Log
http://alsa.opensrc.org/index.php/Aadebug

DO NOT forget to link this Question to your bug report!

Also note, that it is useful if you publish important info about OS and machine using Terminals command: "apport-collect xxxxxx"

,where:
xxxxxxx is the Bug Report number.

Ok,
Now I got the sound.
Thank u very very much

No problemo!
