Codec + Mixer: IDT 92HD75B3X5 - STAC92xx Analog [STAC92xx Analog] Audio device [0403]: ATI Technologies Inc SBx00 Azalia (Intel HDA) [1002:4383] - No sound from speakers or either of 2 independent headphone jacks on HP Pavilion Dv6 Entertainment PC

Where to start;
- I have read and tried numerous threads with similar issues, those using STAC92xx hardware and no solution has worked.
- I have updated alsa and edited alsa-base.conf with every model listed for my device
- I think the number of audio ports, or the current state of alsa-conf may be to blame.

With that I have included the output from Mark Rijckenberg's 12 steps to Alsa sound
(found https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/75353 and https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/79688)

=================================

As I mentioned before my alsa-base.conf is much more convaluted than my SuSE install was (which only had 3 lines and sound worked -- I think an 'install' line, a 'options' line and an 'alias' line. all three referencing snd-hda-intel and using model hp-m4)

At this point I am willing to try anything. If you think rattling a dried gourd and chanting penny lane backwards will help I will give it a shot,

Thanks to all!
