[Bug 637947] Re: no sound devices on current ES2.0 boards

[Emmet Hikory]

I believe the correct way to fix this is by creating a board-specific
driver that will indicate the wire layout from the codec (which driver
exists) to the ports on specific boards.  Failing this, there may be
ways to hardcode the wire layout either (incorrectly) in the codec
driver, or (less bad) by setting quirks based on some other discoverable
factor about the board.

If no kernelspace solution is available, a hardcoded asound.conf in a
separate package (or created by jasper) is is very heavy-handed and
inflexible way to address the issue, and has significant potential to
break other audio paths (e.g. USB audio).  Much better would be to add
codec-specific initialisation into a configuration fragment in the
/usr/share/alsa/ distributor configuration directory.  I'm not deeply
familiar with this, but I believe that adding a
/usr/share/alsa/init/omap4 or similar would be appropriate as a fallback
for buggy kernel drivers (with appropriate conditional inclusion from
00main).
