Sound Problems

[Emil Payne]

First off, let me state that it may be something I did.  Plus, with all 
the things I've tried from reading the internet, things are probably all 
screwed up now.

I am running ubuntu 9.04 installed about a month ago from a Canonical 
CD.  Since then it has been upgraded a few times including three kernel 
updates.

I currently have NO sound of any type.

When booting off the live CD the sound is perfect and I get the following:

===========================================
ubuntu at ubuntu:~$ aplay -l

===========================================

However, when running the installed program I get the following:

===========================================
ehspayne at ubuntu:~$ aplay -l
aplay: device_list:217: no soundcards found...
ehspayne at ubuntu:~$ aplay -L
ehspayne at ubuntu:~$
===========================================


The sound card is the built-in motherboard sound.

Any ideas where to start or what other info to send to this list?
Obviously not a bios problem.  Could it be a kernel problem?

Thanks;

Emil
