Hardware :: 24" LED + Windows POP Sound

Jul 3, 2009

I have a 24" LED cinema display hooked up to a quad 2.66 Mac Pro. Whenever I load Windows 7, there is a single 'pop' sound that comes from the cinema display's speakers. It occurs right after choosing the windows partition in the boot menu. Also, it doesnt occur if I disconnect the cinema display's USB cable. However, this sometimes causes Windows not to recognize the monitor.

This sound never happens when loading the OSX partition.

Windows On Mac :: Sound In Windows Vista (64bit) Not Working Right Under BootCamp 3.0?

Sep 24, 2009

Last night I installed Windows Vista to run a game on here, but I got several issues. I already installed the drivers from the Snow Leopard DVD, but the problems still persist.

The issues are:

1. Sound is very very low and uneven. I have the volume all the way maxed, but the loudest it can go is less than half than the potential volume in Snow Leopard.

2. Headphones don't work. I've tried like 3 pairs of headphones and none of them work. When I plug them in, the sound still comes from the left speaker (I can barely hear the right speaker) on the laptop and not on the headphones. Also, the headphone jack is emitting a red light out of it.

3. The lights on the keyboard won't shut off. I used the F5 key to turn off the keyboard backlighting, and while it goes very dim they won't shut off.


I already tried the suggestions on this thread but none of those fixes work. I need help! Especially with the sound! Anything at all would be greatly appreciated.

I'm running a MacBook Pro 13" from June 2009, 2.26GHz Intel, 4GB of RAM, and an Nvidia GeForce 9400M. I instlled a 64bit version of Windows Vista (OEM).

Windows On Mac :: IMac Sound Quality With Windows?

Sep 23, 2010

I recently got my new iMac 27" i7 and I have successfully installed Windows XP via Boot Camp. I have everything up and running except I believe there's a sound quality issue. When I play music on the Mac OS side it seems very clear and precise. However, when music is played via Windows the sound seems to have deteriorated, almost hollow or more muffled?

Has anybody else experienced this? Is this normal for Windows or this a driver issue?

Windows On Mac :: Windows 7 On Bootcamp: Had Sound But Now Don't?

Aug 18, 2009

So everything was working fine, until this morning when i installed the new 64x Nvidia drivers and the realtec driver updates. In hope of stopping the random freezing i have been getting (the computer completely freezes and i have to do a cold shutdown).

Well i have spent the last 2 hours trying to get my sound back, which stopped working after restarting following the installation of those 2 drivers.

Importantly, when i press F10 or F11 (the mac volume keys) i get no HUD or any change in system sound, this always worked before.

I have tried rolling back Realtek drivers, and also repairing bootcamp drivers via disk and via bootcamp 2.1 vista update download. All unsuccesfully.

I have speaker sound coming out on the EQ but system sound is dead.

Also no sound from headphones.

Applications :: Quicktime - Mov - Windows - No Sound?

Jan 12, 2009

I have this feeling that the forum veterans have likely heard this many many times. So if you have I apologize in advance, I've been hacking away at this for weeks off and on and haven't been able to find an answer. Also wasn't able to find a solution through searching. So... here we go. Issue is, no sound from .mov files on my PC. On my MacBook, the .mov files play just fine, and play just fine on the AppleTV. This is my main media computer, so I store all my movies here (I like VisualHub and ffmpegx much better than anything on Windows I've seen. If anyone has suggestions for Windows, I'm all ears). All my new movies and TV shows are stored on the MacBook, and every now and then I do a move of all that I've watched to here on the Windows desktop where I archive my favorites and keepers. The only problem, is that all my .mov files have zero sound when playing on the PC, though fine on my Mac. So far, I've tried:

- Re-installing everything Apple (even Bonjour)
- Installing all Quicktime components suggested on the site (link)
- installed CoreAAC-1.2.0.573
- installedK-Lite Codec Pack 4.4.2.0
- I also extracted the .aac to .wav to try another format.. the result was 2 hours of dead air
- I also tried the trick with the new update for the AppleTV in inserting a sub 1 sec clip if an .ac3 file into the .mov
- also no sound playing them through VLC

I have seen a couple posts about Quicktime for Windows unable to play HD vids, but a) not all my .mov are HD b) sounded like all the issues were video related.

Windows On Mac :: Low Sound Volume Under Bootcamp?

Aug 26, 2009

So I've been following the MBP forum for their Audio Volume issues because we seem to have the same problem. Check out their issues here: [URL]

There is also an apple discussion here. [URL]

I have a Late 2008 MB running both Leopard and Boot Camp with Windows XP pro SP3. Under boot camp it uses the RealTek driver for the sound card. It is putting out very low volume. Many people have posted similar problems with Vista and windows 7.

Here's the test I did to confirm. I made a 1kHz test tone audio file and played it out of OS X. I connected the output of my headphone jack to a volt meter and measured a little over 1V or 1000mV. I switched to Windows and played the same file. This time I measured 280mV. This proves that the RealTek driver is not sufficient and does not measure up the full potential of the Macbook.

I've called apple on the issue and they say that it is not their problem and they do not support it. Even though they advertise that Windows is fully functional under boot camp. The solution for the MBP was that someone modified the INF driver file. Unfortunately, Apple uses a different chip in the MB and this solution will not work. I tried it.

Windows On Mac :: Boot Camp Sound?

Oct 16, 2009

I've recently installed Windows XP SP3 in bootcamp on my iMac so i could play some windows games, and there's one problem: the sound is coming out of the built in speakers with a horrible noise in the back instead of from the speakers i have plugged in. The RealTek driver recognizes that the speakers are plugged in, but doesn't use them. Now I've tried to connect my ipod headphones, and they don't work either! What sould I do?

Windows On Mac :: No Sound Under XP Operating System

Dec 2, 2009

I just installed Windows XP (SP2) on a brand new 27 inch iMac (OS-X 10.6.2) with bootcamp and also installed the bootcamp drivers from the included Mac OS-X installation disc (resulting in bootcamp 3.0 installed). Everything works fine, but... there's is NO SOUND under Windows. When I look in device manager all seems fine but again, I have no sound under Windows.

Windows On Mac :: Sound In XP Using Boot Camp

Jan 21, 2010

I have tried everything to get this motor running. I've spent so many hours on this, and now I've simply given up and hope that someone here can help me, before I go out and kill myself in pure frustration.

I don't have any sound at all after having installed Windows XP on my iMac 24. I have tried two different versions. One with SP3, and currently one with SP2. Since I read that a lot of people had trouble with the HD audio in SP3, and the fix didn't do anything for me, I figured I might as well try SP2.

Who cares, right. This doesn't work either though. I've downloaded the fix refered elsewhere on this site, and reinstalled the drivers. I have disabled, reenabled, uninstalled, reinstalled, updated and so forth so many times I've lost count. I think the Windows I'm running now is the fourth reinstall of windows, and I'm absolutely lost.

What's even worse is that I have an external sound card, a presonus firebox, which I have also tried to install several times. I reckonned that it might help to install an external sound card. But even this doesn't work. The light is blue, when I'm installing drivers, and updating firmware, but goes red after this. But whatever. If I can just get the standard output working.

Probably a very n00bish question, but would it matter, that I'm using a friends Leopard disc, which is used for a laptop? This, the fact that it's not my own disc, is really the only thing that haven't fit exactly into all the guides, and troubleshooting.

Windows On Mac :: How Do You Turn The Startup Sound Off

Apr 25, 2010

I have a 3 year old MacBook Pro, so I decided to experiment with Bootcamp. I changed it completly to Windows. Happily it worked, however there doesn't seem to be a way to mute the startup sound. I've searched the internet for answers but the problem is, but all the advice I find tells me either to mute the computer before turning it off (which unfortunately doesn't work), plugging in headphones (also didn't work), or downloading a mac application which I obviously can't as I'm in windows.

Mac Pro :: Can't Get 5.1 Surround Sound Running Windows 7

Dec 11, 2014

So I'm running bootcamp on my Mid-2010 Mac Pro and I can't get Dolby Surround Sound to run from the Realtek HD Audio Manager. Is there a way to produce true Dolby 5.1? I understand this may be more bootcamp related than to the actual hardware itself but I figured this is the best place to start troubleshooting this. 

Info:
Mac Pro, OS X Yosemite (10.10.1), Mid-2010 Quad Core

Windows On Mac :: No Sound After Reinstalling Win7 On IMac

Sep 21, 2010

Got an '07 iMac, and just reinstalled Win7 on it, while playing around with the partition sizes. Before, everything worked fine. Now, I have no sound (though, if I strain my imagination, I think I can hear something). According to Windows, everything's working fine; says the driver is functioning just as it should. I've reset the computer, no dice. I've checked things in OS X, and its just fine.

Windows On Mac :: Low Sound Quality In Vista Ultimate?

Jun 9, 2008

I'm running Windows Vista Ultimate using Bootcamp. It runs fine with just a couple of anomalies.

First is that the sound quality is quite poor...almost like AM radio...I've tried installing the latest Realtek drivers but it's made no difference. I've stuck it onto "Rock" preset and that has improved things slightly but I was wondering if there was a proper fix for this?

Also, even though Vista see's that I have dual processors and correctly reports them (and I get two CPU usage graphs under task manager) applications such as dBpoweramp don't see it and run in single processor mode? Aga

I'm running a 24" 2.8GHz iMac with 4GB Ram.

Windows On Mac :: Boot Camp Sound Is None Existant?

Feb 21, 2009

I literally registered to these forums 3 minutes ago, so if this has already been covered and solved than it would be great if someone could point me in the right direction.

When installing the necessary drivers from the Leopard install disc I get an error reading something to the tune of "another instance of this install is already in progress.

Please try again when it is finished." Now, that is not exact, but it's pretty close. I've learned that this message is tied to the audio drivers needed for Windows, and I've confirmed that by going into the control panel and seeing that the system does not register any sort of audio input or output.

I've tried a few google solutions for this problem, including: downloading some sort of Windows patch, downloading drivers from the Realteck(I think that was it) website and reinstalling the drivers from the DVD. None of those has fixed the problem, and I continue to get the same error but of course see no other "instance" running on my machine.

Windows On Mac :: Sound Distortions On Left Speaker - How To Know About It

Dec 12, 2009

Since updating the Windows 7 drivers with the Snow Leopard BootCamp version 3 I've noticed strange sound distortions coming from the left speaker of my iMac. This seems to be a driver issue because both under OSX as well with older drivers which came with Windows 7 RC1 the left speaker functions properly.
