Stan,
Thank you for spending time to look at this issue.  I owe you a drink, when you are in the chicago area let me know and I'll treat you to one.

Ok, so I will check with the developers an see what can be done to correct this.  Thank you.

I think your problem is a misidentification of your sound chip.  The 
model being used for your 889A appears to be incompatible, thus all 
the errors above.  It appears that the macpro ALC885 is being selected 
before it gets to the choice for the ALC889A.  Perhaps a developer can 
look into this.

!!HDA-Intel Codec information
!!---------------------------

Codec: Realtek ALC889A


!!Aplay/Arecord output
!!------------

APLAY

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC885 Analog [ALC885 Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0

One shows ALC889A and the other shows ALC885.  In the driver code 
there is a comment to the effect that the 889A is best handled as an 
ALC888, yet the macpro is listed under the ALC885.

I am not a developer so can't go beyond this, but it seems that there 
is a problem.  There should be a macpro under the ALC888 as well as 
the 885.

Here are the model options for the two candidates
