** Description changed:

  Found there is no internal speaker output from hp touchsmart 600-1005xt
  in all releases of Ubuntu 8.04 to 10.04LTS with updated alsa-base (on
  1.0.22.1 in Lucid now). All outputs & inputs work except the Internal
  speakers. I Checked all alsamixer levels, I have also noticed the
  nodeid's it seem to be mapped 0x15 - 0x0d - 0x03 (21 - 13 - 3) for
  internal speakers which gives same results (no audio) in osx
  Applehda.kext. The Headphone nodeid's of 0x14 - 0x0c - 0x02 (20 - 12 -
  2) seem to work in all Ubuntu Dists & OSx as well. Windows 7 Driver
  everything works of course. Is Bios sending wrong pin configs for
  internal audio? if so what would the resolution be?
  
  here is my alsa-information from alsa-info.sh attached, My only guess is
  the pin configs how do you change them in alsa driver & how could I get
  the correct ones if the bios was sending wrong pathmaps? I should also
  note I've tried most of the model flags in alsa-base.conf in the alc888
  documentation & rebooted countless times, model=auto shows the internal
- speaker but no sound.
+ speaker but sound comes out microphone plug.
