The port was suffering bit rot deriving from differences between the

previous pcm driver and newpcm.  This replacement port adds newpcm
mixer support and brings port up to date with the current rat release
(4.2.9).

+ 	- Fix labelling of transcoder input/output ports

++v4.2.9p1 - Added auddev_newpcm.[ch] with newpcm style mixer control.  Includes
++	  support for loopback and preservation of mixer settings so mixer is
++	  returned to original state upon exit. [oh]
++
++	  Note: both driver interfaces (luigi, newpcm) are pulled in
++	  by configure and this is possible whilst luigi pcm and
++	  newpcm maintain the same function call interface.  This may
++	  break in future.  Both are necessary because mixer operation
++	  is not consistent between the two interfaces.

+-	- Loopback support is broken on FreeBSD newpcm driver.
+ 	- Broken auddev_pca with adding of audio interface conversion code.
+ 	  FreeBSD 3.1 pca audio does not seem to work anymore.

++v4.2.9p1 - Added auddev_newpcm.[ch] with newpcm style mixer control.  Includes
++	  support for loopback and preservation of mixer settings so mixer is
++	  returned to original state upon exit. [oh]
++
++	  Note: both driver interfaces (luigi, newpcm) are pulled in
++	  by configure and this is possible whilst luigi pcm and
++	  newpcm maintain the same function call interface.  This may
++	  break in future.  Both are necessary because mixer operation
++	  is not consistent between the two interfaces.
