I downloaded the latest development drivers, lib, and utils (1.0.18rc3) and compiled and installed it again. Next I made sure that the /etc/modprobe.d/sound had the following line: options snd-hda-intel model=imac24
and first I checked the gui tool called "PulseAudio Volume Control" from my "multimedia" section, and it crashes!
Next I tried the aplay somesound.wav file from the command line, it my Mac Pro sings!!!
I don't know what the PulseAudio issues are, but ... oh well!!
Next I checked that Amrok works using the alsa engine, and it does!!
If I plug in a headphone set, and I play music again it comes out of the MacPro speaker only, but no from the headphones.
Do you have a handle this, if you guys have some links for me to read, please send them my way!
Thank you. // Sal Aguinaga // Northwestern University // Evanston, IL

============================================== Trying to figure out where to add this "model=macpro" and it looks like it should be in a file called modprobe.conf or an options file under /etc/modprobe.d/
but I don't have (with my installation -- fedora {9} ) those files, do you have any input on this?
You can create any file, typically, /etc/modprobe.d/sound or so. Put the following line there
options snd-hda-intel model=macpro
Then reload the module, check the sysfs file /sys/modules/snd_hda_intel/parameters/macpro to see whether the specified option was really passed properly.

below are the only files I have.

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:
sudo cat /var/log/messages | grep ALSA Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_intel.c:1810: chipset global capabilities = 0x4401 Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_intel.c:749: codec_mask = 0x1 Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Surround Playback Volume, skipped

These messages are harmless. It's just information from the driver, enabled only when you build it with CONFIG_SND_DEBUG_VERBOSE=y.
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.
Well, ALC882, ALC885 and ALC889A are almost compatible. In the driver, they are all handled in the same routine.
There are a few models for intel macs with ALC88x. Try to specify either model=macpro, model=mbp3 or model=imac24 as the module option of snd-hda-intel driver.
