FYI, I did finally manage to find the KDE mixer and run it. I found that the 
"master" was muted as was the PCM as well. However, even after unmuting it, 
I still can't get any audio. I tried the suggestions on the Fedora project 
page, but that didn't help either. I found several entries in alsa.org 
about the same hardware, all using the same script, but I can't find a 
single article about changes needed to get it to work.

As I say it *used* to work, but now it doesn't, and the ONLY change has 
been from F14 to F15. NO hardware changes of any sort have been made!
