Subject: Multiple Codec Problem With Intel HD Audio

Hi Takashi-san,

I have a custom Atom Poulsbo based board on which I am running 2.6.34.
The board has an ALC888 connected to the Intel HD Audio controller for
the main speakers and another ALC888 on a daughter board connected to
the same controller for additional headphone and mic jacks. On boot I
get the following:

hda_codec: ALC888: BIOS auto-probing.

The headphone and mic jacks don't work.

I have noticed that in the kernel Intel HD audio documentation, you have
mentioned:

"In theory, there might be multiple audio codecs, e.g. for analog and
digital outputs, and the driver might not work properly because of
conflict of mixer elements. This should be fixed in future if such
hardware really exists."

I believe this is the problem I am hitting? Is there a fix available for
this? I have attached the codec info from /proc.

P.S: The hardware is okay since in Windows I can get both codecs to work
(one active at a time) even though I have to manually change the default
hardware setting.

Regards,
David.
