Finally got my Mac Pro.

When it showed up, there was an issue with sound (rear analogue audio was switched off, headphone and speaker both active) which I easily fixed by changing the settings in the sound control panel...sorry, preference pane! So now my powered  (external) speakers work fine.

Thing is, the problem persists when I boot into XP: I need to do the same tweaks in the XP sound control thingy but the problem is I can't seem to find the correct checkboxes to do it. It looks very much as if the audio hardware on my Mac isn't 100% supported by the BootCamp drivers.

Is that likely? Is there an easy fix I'm missing? Anyone know about some 3rd party doodad that will let me see my speaker output?

I've had no problem with the front headphone jack or with my old USB soundsticks in Windows. I don't know about the back minijack.

This is somewhat irrelevant, but people haven't had much luck with the Mac Pro audio chipset in Linux yet.

I know the answer but I'm not going to help because you have a newer computer and a more powerful computer than I do and I want you to suffer and wallow in your pasty skin bag while tearing at your hair.

And that is all the help I expected.

What say you & me have a computer bake-off.? For pink slips. Mano a mano. 14 hours of Prey demo and the hottest graphics card wins.

Yeah?

Actually, maybe not.

Does the front headphone jack work for you? It works fine for me. If it doesn't work, try the bootcamp driver cd. The Realtek Audio drivers seem to work fine for me. Next time I boot into windows, I'll try and find out more information.

Yep. Front headphone works in X & XP: XP 'notices' when I plug something into it. XP also 'sees' me plugging something into the line-in jack bit not the line out. The line out works 100% in OSX but here's a thing - When I restart, the startup chime comes out of the internal speaker. Every other Mac I've owned sends the chime out of the line out. I think the line out is only being 'switched on' by the preferences I've set in OSX, which only come into play once the OS has loaded . I need somehow to affect the (for want of a better term) BIOS of the machine. I bet there's some terminal craziness to do that will nail it. If only I was clever enough to figure it out.... :blush:

It turns out that I'm not the only person with this issue. I've got a thread over at MacOSXHints with a bunch more information if anyone feels charitable and wants to help me out. :)

There are already a couple of threads about this over at the Apple forums: Looks like quite a few people with Macs like mine are in the same boat.

hmmm... looking at a couple of them, it looks like there is no solution other than to either reinstall the drivers or reinstall the entirety of XP... neither of which is a foolproof way of fixing it.

If it was a certain fix I'd probably reinstall: There's only XP & HL2 on there.

Seeing as how it looks increasingly as if it's a flaw in the BootCamp drivers I think I'll just live with the headphones!

I finally got around to reinstalling XP, and loading up the Boot Camp drivers. My rear audio port works fine.

You're almost certainly right. It's the only realistic fix. Maybe when I finish Half-Life 2…or someone tells me where the saved games live!

A sinister postscript:

Bought an extra SATA drive just for Windows (it bugs me if any RAM or PCI slot or drive bay is empty in one of my machines!) and BootCamped it, installed a fresh XP[SP2] on there.

Exactly the same fault.

Almost.

If I remove the rear audio jack & reinsert it the action is recognised by XP and maybe for a second or so I get audio out of the speakers before it dies again.

Which almost says hardware but the same hardware is performing perfectly under OSX.

Which means....


Well, honestly I don't know what it means, but it's quite the most irksome thing in my world right now.

I guess I should be thankful that I have such trivial problems and get used to gaming with headphones on, huh? :)
