I've been able to test this (snapshot as of two days ago, reports version
number 3.8.0-rc5+ via uname).  As expected there have been some

Things which work:

 * "Headphone Jack Mode" allows switching between "Headphone" and "Line
   out".  Both of these mode settings appear to work.

 * There are separate "Headphone" and "Speaker" volume controls.

 * The "Headphone" volume control influences the headphone jack volume.

 * An "Auto-Mute Mode" control appears in alsamixer (it was missing on
   earlier versions).

 * Alsamixer recognises the presence of two ADCs, giving "Capture" and
   "Capture 1" controls, with corresponding "Input Source" controls.

Things which don't work or are missing:

 * "Headphone Jack Mode" lacks options to enable various "mic" or "line in"
   modes (all of which are possible on this system)

 * The "Input source" controls don't offer the "headphone jack" as a
   possible source.

 * The built-in speaker is completely silent under all situations I have
   come up with.  The setting of "Auto-Mute Mode" has no effect, neither
   does a manual unmute of the "Speaker" volume control.  While I don't
   personally care much about this I suspect others might.

 * As eluded to above, the "Auto-Mute Mode" control appears to do nothing.

 * There's no "Mic Jack Mode" control to control the mode of the "mic" jack.
   This jack supports line-in mode as well as the various "mic" modes which
   give varying bias voltages.

Is there further information I could provide or other tests I could do to
help address the "don't work or are missing" items?
