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.
Aaaaahhh! That was refreshing! ;-)
Ok, so I will check with the developers an see what can be done to correct this. Thank you.
You're welcome. We are on the developer's list, so I will change the subject to reflect that there was a bug. I was going to wait a day or two to see if anyone paid any attention, and then do it, but it won't hurt now.

Hello Stan,
This is awesome I did find the problem it's listed in the /var/log/messages under ALSA.
- When I bring up the "Pulse Volume Control" gui, the first tab "Playback" comes up empty, and grayed-out is "No Streams Available"
- aplay does not produce sound, period!
- Amrok's welcome sample does not produce sound out of the std tower speaker or the headphone jack.
I didn't notice anything strange on the output of the alsa-info.sh file, but when I checked the var/log/messages, this is what I found:

Let me know if I should send something else.

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
