[alsa-devel] [Fwd: [Alsa-user] Intel Poulsbo(SCH) chipset does not recognize Adi 1986 codec under linux]]

[Tobin Davis]

If the system you are referring to is a development platform, then it is
possible that the jumper settings on your sound board are not configured
correctly.  One simple test is to swap sound boards.  Another thing to
look at is the bios settings.  The mainstream alsa driver should not
care about the chipset revision.  But if the audio hardware is
misconfigured, that would cause it not to work.
