With driver issues I've learned that you likely only have the same 
issue when you share exactly the same hardware model(s). And sound 
issues can be symptoms for a great variety of problems.
In Steve's case this seems to be the issue that Ubuntu leaves the 
sound card in a state that a very strange driver configuration can't 
deal with (whereas both Ubuntu and Mandriva can).
In your case I'd say it is a symptom for Ubuntu's inability to 
trigger a proper reboot.
I'm not really great with hardware problems, and I don't have any 
experience with Sonys, but if you'd like I could try bouncing some 
ideas off you to see whether we could find a workaround. You could 
either start a new thread or try mailing me privately.
Just as long as you don't start making ridiculous claims that your 
firefox is still running after a reboot... :-D
