Hi Rick,

The laptop model is actually a P105-S6147, not a P107-S6147 as my 
subject line is erroneously stating. I had recently done a BIOS update 
to BIOS version 4.00 for this machine. When I looked in the BIOS 
options, I couldn't find one for enabling on-board sound. And I can't 
remember whether I tested the audio under Windows Vista before, or 
after, I did the BIOS update. I think it was before.

Also, I'm fairly certain there is only one keyboard shortcut for the 
audio, Fn-and a little graphic for speakers, which seems to mute the 
"Master" control or turn it back on. I'll double-check the 
documentation. Pulseaudio is still complaining that it can't find the 
"Capture" control.

Could I have made a mess of the audio with the BIOS update? Perhaps I 
should backgrade the BIOS.

Bob
