Updated the laptop to 8.10RC and got the hardware mute switch repaired.
The original problem description is updated accordingly, and the
"rephrase" posted above can be ignored.

I don't seem to be the only one who has no sound on the speakers:

** Description changed:

  I purchased a brand new laptop model: HP 6930p with Intel 4500MHD
  graphics and Intel 82801I (ICH9) HD Audio, and I installed Intrepid with
  the latest updates. I have the following problems:
  
  - The buttons for controlling the brightness (Fn F9/F10) don't work. xev does 
not show any events for these buttons. Trying to write values into 
/proc/acpi/video/GFX0/DD0?/brightness has no effect.
  - Upon connect/disconnect the AC power, there is a little pop-up on the 
screen indicating that the brightness goes up or down, but there is no change 
in brightness.
  - If booted with AC connected, the brightness is high; if booted on battery, 
brightness is low. This won't change until reboot.
  
  - Fn F8 is supposed to display a battery status bubble, but it doesn't.
  sudo acpi_fakekey 236 has no effect either. When I press Fn F8, xev
  reports keycode 244.
  
- - Once Gnome starts, the mute light comes on. I cannot switch this off
- using any of the various volume controls and I have no sound on the
- front speakers. (Since the physical button has a problem as well, I have
- no way to un-mute. However, when I boot from the original Vista disk, I
- can control the mute from the GUI and I do get sound.) Audio output on
- the headset jack is ok, and I can mute the sound from the GUI. It seems
- that the mute light reflects the front speakers only. ALl volume up/down
- controls (physical and GUI) seem to work fine.
+ - There is no sound on the built-in speakers. Headset, on the other hand, is 
ok.
+ - Clicking the hardware mute button has no effect on the settings in the 
Gnome volume manager, and muting/un-muting in the Gnome volume manager has no 
effect on the mute LED. The volume settings, on the other hand, work ok.
  
  I do not see any of these problems when I boot my older laptop (HP
  NC6000) from an Intrepid CD.
