Comment 12 for bug 574137

Just for the record.... You can see from my original bug posting that my system had a Realtek ALC272 card.

Unfortunately (or perhaps fortunately) the screen on my NB30500F died (backlight ceased to function). I plan on replacing the unit soon with an identical one. It will take me a day or two to install Ubuntu. I will report back as to whether identical sound problems occur for a completely new install on a new machine.
