IMO.... its fixable.... What users have done here shows it. It just needs a programmer assigned to the task...

Audio Decoding KILLS MacPro (2009) green factor

What a joke. You waste countless hours on the phone, weeks of troubleshooting, and you get a response like that. I too received responses like that over and over again. If you spend another few weeks escalating your case, maybe they will tell you to repair your permissions..
Ugh... yep, mine too. I can't believe it but the CPU shot up by 10 degrees Celsius almost immediately after I started playing music. Thanks for the warning, I'll transfer my library and use another 'puter to handle music.
Isn't it a little bit silly to use a whole other machine for music playback just to keep your CPU 10 degrees cooler? This sounds like a major overreaction, and ultimately an even bigger waste of electricity and heat.
yes, as have i. the appropriate kexts/files are in the combo update to update any computer (within specific OSs of course).
Seeing as my Macbook Pro with screen off draws 28W compared to the 72W the Mac Pro draws (along with the additional time required to compute tasks) yes actually having two computers to do the job of one is more efficient...
I'm now doing the same as you CR.. Piped the Macbook Pro into my speaker system with a Y cable.. Pretty pathetic isn't it?
Have to agree. Makes it difficult if you want to work with video on the high-end workstation. For those who are interested:

I sent an email to Steve Jobs (sjobs@apple.com) and I actually got an answer from Cork/Ireland:
I'll try and translate this for you:
Hoffentlich wird dies was,danke

Man darf gespannt sein.
Anyway, what's the deal with the FW drives?
I just tested my machine with regard to heat issues while transferring data from an internal, to an external FW800 drive. Even after 50GB, which took a while, the CPU temperatures remained on the same level.

Good work.. I sure hope it leads to something good.
Perhaps I am getting too cynical, but I fear this is just the beginning of another frustrating chain of communication that involves you explaining the whole situation again to somebody that knows absolutely nothing about software / hardware, then having somebody promise to look into it for you, only to never hear back, or worse yet, find out that it is "within limits"...
I've lost all my faith in Apple..
Actually, in my mail to Steve I explained the situation in detail, linking to MR, MacNN, MU and the Apple Discussion Boards so I expect that this lady is informed about the situation. Well, she is going to call me tomorrow, I will let you know about the outcome.
Sounds like Steve passed you off to an "escalation expert"--we had people like that at my former company. She may or may not take the time to read all the background info but it's very likely she'll have enough power to make sure the engineers look into it. (Unlike your average applecare rep., etc.)
Just stay polite and try not to sound like a nutjob.

I believe Apple's term is the "executive customer service" team. I've dealt with them after writing to Jobs for a 1st gen. MacBook Pro that went through almost a dozen repairs and they did a CRU for me (Core1 to Core2).
But yeah, stay brief, don't sound crazy, and try to emphasize things that appeal to Apple, like how this isn't green of them, how it really diminishes your faith in their ability to stand behind their product, etc.
I seriously hope nobody is under the impression that sjobs@apple.com actually goes to Steve's email box!
With that said, I emailed Steve just over two years ago regarding my G5 PowerMac's coolant leaking out and frying both CPUs to the tune of $1,500 in repair costs. Apple paid for the repair through a local repair facility even though the machine was three years out of warranty. Wasn't that nice?

The Maya 44e arrived today. As a baseline, I started iTunes and played songs for 15 minutes. With iStat reporting an ambient temperature of 73 F my CPU temp climbed to 113 F (sorry, don't use Celsius..). After installing the card and struggling to find an old RCA connector so I could play back through the Maya, I am very happy to report that the CPU fluctuates from not registering any temperature change at all to increasing 2 F.
So from my perspective, this card remedies the playback issue. Users performing file transfers from external devices are still without a solution. I would venture a guess implementing a solution which uses an interface on the PCIe bus would also remedy the situation, but we only have so many slots....
So someone with more intelligence could look at a schematic of the motherboard and figure out why the audio, USB, and Firewire on-board solutions cause the cores to run hot.
Please forward any questions you have regarding the card.

Apple doesn't publish the schematics, nor are they actually needed, as this is a software problem (OS X), not the hardware.
It's been tested by running Windows with the same tasks. No heat, increased power consumption, or performance loss on the same systems. So it's definitely not the hardware.

Nanofrog - I have been following this thread as long as you have - I have an impacted MP. I have read the posts about the issue being absent from Windows.
My point was this - whatever driver/component Darwin uses to pull info from the ICH10 interface is not as optimized as the driver pulling from the PCIe 4x lanes (this is a Gigabyte schematic, not Apple)
The thread's quite long, and it seems to be forgotten, given the direction of the posts.
It's not enearly as bad RAID /= backup though.
