href="http://www.ubuntu.com/">Well I received my new Dell Inspiron 1525 and thought I would upgrade to Intrepid right away because I need empathy voice (gtalk). I hit AltF2 and typed in "update-manger -d" and received over 1 gig of data. Restarted and no sound. SAD! I phoned Dell at their Ubuntu support number 1866-662-1947 and they tried to pass me off to windows support because my Express Service Code told them I had a windows laptop. 35 minutes later they agreed to help me asked me to go to termial. Waiting eagerly to type something they instead sent me to linux.dell.com and tried to get me to click on Ubuntu on Dell and type "sound" in the search field which got me to sound problem page - still no sound. SAD! So, Dell help told me it was not a hardware issue so they couldn't help me. SAD Believeing in the Open Source Idea I thought I would got to Launchpad so see if this was a bug. It is. GREAT! typing in "pulseaudio -k" tells me the kernel as "failed to find dlopen loader."
Go to System > Preferences > Sound and change every field to ALSA
Now I am happily using gtalk to do my VOIP over XMPP
