applemacman Posted February 25, 2007 Share Posted February 25, 2007 I recently dual booted my MBP to use OS X and Vista. In OS X, the comp runs perfectly fine. In Vista, however, the computer emits this very high pitched whine. What is Vista doing with the processor that Mac isn't? I've taken my MBP for repairs because of whining (in OS X) twice before, so I'm in no rush to truck out there again. Is anyone else having this problem?

hecker Posted February 26, 2007 Share Posted February 26, 2007 It may not be the processor but the LCD screen. Did you check what frequencies the display is set for in Vista and OSX?

cringemaster Posted February 26, 2007 Share Posted February 26, 2007 Sounds like the fan... Had a similar issue with vista on my mini and with linux on an older mac.

applemacman Posted February 28, 2007 Author Share Posted February 28, 2007 I hope that it isn't the fan, as I am on my third one. (I got the most recent 2 weeks ago.) Â I'm not sure how to check the screen frequency, so if you know how, could you please instruct me? Â Is anyone else using Vista on a MBP? Do you have this problem as well, or is it a case of isolated incidents?

sandmanfvrga Posted March 1, 2007 Share Posted March 1, 2007 Maybe that without OS X you don't have the drivers/software to run the fan right. Also Windows may tax it more. Could be a combination of both. Link to comment https://www.insanelymac.com/forum/topic/43557-macbook-pro-whine-on-vista/#findComment-314065 Share on other sites More sharing options...
bushwakko Posted April 11, 2007 Share Posted April 11, 2007 I have the same problem... scrolling relieves it, hehe. I think this is the same issues they had in osx earlier too, but they probably fixed it in software. to bad they havent done it in vista yet. Â EDIT: I just found out what it was, I was using my headphones, when I pulled them out it stopped. So I started playing a little with the sigmatel settings. I found that if you enable the Power Saving stuff there the whining starts again. So apparently it whines when you enable power savings or use headphones. I'm guessing its a driver issue..

bushwakko Posted April 18, 2007 Share Posted April 18, 2007 I've tried every damn driver I've come across for the sigmatel HD thingy now, and none work except the ones on the boot camp cd. That one has the whine when I insert headphones or turn on power savings though. Where do I file a bug on this, so Apple can fix it in the next bootcamp release?

Â Hi bushwakko, Â I have the same problem and thanks for finding out the Sigmatel thingy. However, I am wondering why this has to do with the sound card because it seems like the same whining problem as before. I have a C2D 15" and the whining is very light; it is noticeable only when I am working late at night. The whining goes away as long as I play some video. Also it will go away for about 2 seconds if I click some folder in Windows Explorer. In short, when CPU is idle, it whines, but I think it is not as loud as the earlier model. But now I can confirm that the disabling the Sigmatel power saving mode also make the whining go away. Weird! I don't have how much power the sound card is drawing, but I think it is worth it. The whining isn't that loud but still noticeable and annoying at night.

enj0y Posted June 8, 2007 Share Posted June 8, 2007 out of curiosity... how much battery time do you get with the power saving feature of the soundcard driver enabled / disabled?

enj0y Posted June 11, 2007 Share Posted June 11, 2007 thanks for the informative contribution glassjaw. on another note... the whine goes away on my machine under osx if i enable bluetooth and connect a device.

linuxfan66 Posted June 20, 2007 Share Posted June 20, 2007 Is the whining noise caused by darWhine? Seriously though, fan whine a problem on quite a few notebooks, even UMPCs.

bushwakko Posted June 20, 2007 Share Posted June 20, 2007 it isn't fan whine. it's something else that whines when under low load when the sound chip is enabled. if you uninstall the sound driver the whine goes away all together, so i'm guessing that the sound driver needs to be tuned. It's probably why there is no whine in osx. Link to comment https://www.insanelymac.com/forum/topic/43557-macbook-pro-whine-on-vista/#findComment-390091 Share on other sites More sharing options...
Moduliz0r Posted June 20, 2007 Share Posted June 20, 2007 My CRT monitor makes a high pitched whine quite often. It's irritating but you get used to it. When I had a laptop, (I only had Windows XP on it) if you connected it to external speakers you'd get a low buzz which changed depending on CPU load. You could tell when it was up to something because it would buzz loads.

enj0y Posted June 20, 2007 Share Posted June 20, 2007 @bushwakko: does the whine go away when you use the windows calculator to compute 30000 n! or in other words if you use the CPU?

bushwakko Posted June 20, 2007 Share Posted June 20, 2007 dunno, but it is affected by cpu load. Link to comment https://www.insanelymac.com/forum/topic/43557-macbook-pro-whine-on-vista/#findComment-390230 Share on other sites More sharing options...
enj0y Posted June 20, 2007 Share Posted June 20, 2007 @bushwakko: so how much runtime do you get out of your battery using vista? I am curious because under WinXP i dont have the whine, the soundcard settings dont have any energy saving options and i only get ~2h out of the battery. I suspect that the whine is related to some CPU sleep state which cannot be reached under XP at all.

bushwakko Posted June 20, 2007 Share Posted June 20, 2007 i'm not sure, but it' less than in osx. i'm guessing 2h is about right. Link to comment https://www.insanelymac.com/forum/topic/43557-macbook-pro-whine-on-vista/#findComment-390396 Share on other sites More sharing options...
