13-inch MacBook Pro: Low audio volume under Boot Camp?

Thanks for that!
Is there anything you can do about vista/7 spdif, or the flaky microphone that doesn't work for third party programs in windows?
 
Vista and W7 64 and 32 bit fix.

Using Henry's suggestions, I made edits to the INF file that limit the volume on the headphone jack because it is too loud and remove the limit on the speakers. I also wrapped it all up in a 7Zip installer package for both the 32bit and 64bit flavors of Vista and Windows 7. The only downside is that the red light is always on but this is probably because the functionality to turn it off when there is nothing plugged into the headphone jack is added on later by Apple and not a standard feature of these drivers, we'll have to wait for Apple to fix their driver. Thanks again to Henry and ChristianZ!

In order to use these, just install them! No need to edit the INF file! If you were using the previous INF edits, just install this on top, these are much better because the headphone jack has normal volume.

Due to popular demand, I have created a variant of the modified XP driver that also turns off the optical S/PDIF output. It's available in the same place as before.

Thank you so much for the great fix!

@henry128:

Thank you VERRRRY much for your fix, henry.

Apple is still unaware of this problem, but thanks to your fix, I can crank up the volume under WiXP SP3 almost loud enough to have a little dance party in my living room.

Great work!

Cheers,

Low audio volume with RealTek driver

So I've been following this thread for quite some time. I'm having issues with my macbook late 2008. Under bootcamp it has the RealTek driver installed and has the low volume output. I tried removing all instances of the Realtek driver. I installed the Cirrus driver as instructed, but got no sound.

Am I missing something? I can't find my original install disc for the macbook so I couldn't try any of the other drivers. All I found was what was available for download. Could this be my problem? Do I need to install the Cirrus driver from the original install disc first? Then modify the INF file???

Any help here would be much appreciated. Thanks!
 
I would like to add I installed the CirrusAudio driver in Vista and have low volume. Also I should note my headphone output does not work.

Anyone?
 
I'm with these guys. I have MackBook 13" Unibody late 2008 with Windows 7 Ultimate 64-bit Ultimate installed on it.

If I install the latest Realtek, I have audio but it's low. If I uninstall it completely and then install the supposed "fix", it says I have working audio, but I have no audio output whatsoever. I've tried rebooting, I've tried installing the Cirrus driver fix over top of the Realtek with the same result, no audio output. Also tried 32-bit drivers. I couldn't get it to work in Vista Ultimate 32-bit either. You name it, I've tried it. This is probably aimed more at XP users.

Any ideas other than everything listed in this thread because none of it has worked for my configuration listed above.
 
This thread is for the 13 Macbook Pro, not the 13 Macbook. They use different audio chips so the fixes posted here won't work.
 
Just wanted to add my voice of thanks for the driver fix. Its nice to have sound working properly in XP again.

Hopefully with Snow Leopard there are new (fixed) drivers for Bootcamp. Guess we'll find out Friday, though they might hold off till Win 7 is out I guess.

There are no threads under the macbook forum. This is the only one we could seem to get traction on on the subject. I know they have different chips, but I was hoping that someone here might have a fix for us.

I'll keep digging on the macbook forum, but no one there seems to be interested in the topic. Either that or they're not as smart as the MBP users. ;)

Thanks for the easily installed fix. It's sad that:

a. The sound quality is still awful.
b. Apple haven't fixed this yet. Hopefully they will eventually...
 
Just installed the new drivers that come with snow leopard and the sound it still the same low volume, with 3x more sound coming from the left speaker.. very dissapointed
 
I kind of need help.

Ok,
So im in the same boat.
I have my iMac and my MacBook Pro running BootCamp ( Windows 7 )
On my iMac everything runs smooth all the keys work. Sound is prefect.
On my MacBook Pro there's a different story.
Keys don't work, i had to download drivers to get Graphics card to work good.
The audio don't work at all!
Just nothing seems to be working!
But everything works on iMac, Help ?
 
A Theory I Have; What do you think?

Hello Everyone,

My name is Mark.

Like everyone else, I have the same problem with my MacBook Pro 13” with Boot Camp, Snow Leopard, and Windows 7 Final release.

As a low vision person, I use an audio screen reader to interact with Windows 7 so this sound problem is crucial to my use of the device.

I have not yet tried the fixes posted in this thread although I will most likely do so after testing the following theory I have about getting the system sound to function correctly.

When I could not get Windows 7 to work correctly via Boot Camp, I removed the Windows partition and installed VM Ware in Snow Leopard.

To my surprise, the sound card worked perfectly including use of the function keys to adjust the sound.

After getting Windows 7 tweaked just the way I like it, I decided to accept the recommendation to install the VM Ware Tools which is supposed to enhance the virtual machine experience. Well, after installing the VM Ware enhancements, I had no sound whatsoever. I was astonished and quite pissed off, to say the least.

Just before losing my ever-lovin’ mind, I went into the Windows 7 device manager and chose to roll back my sound driver. Thank goodness, this solved the problem.

As has been noted in this thread, Boot Camp uses a Cirrus Logic driver. However, upon rolling back my virtual machine, which removed the VM Ware sound driver, I discovered that the driver my virtual machine works with is one by creative Labs as listed below:

Creative AudioPCI (ES1371,ES1373) (WDM) >
Version: 5.2.3633.0
Date: 6-18-2002
Provider: Creative Technology Ltd.
Class: MEDIA
Setup Information: oem1.inf
Setup Section: ES1371.NTx86

So, I downloaded a driver extractor and saved the driver to a folder on my network.

My Theory is that if I install this driver in Windows 7 running under Boot Camp, the sound will be fine.

What I plan to do, and I would appreciate any feedback on this, is to once again install Windows 7 via Boot Camp and then use this creative driver.

Do you think this will work?

Mark
 
Yes I do think it will work. I am going to try and find the driver and Ill try and install it myself. Thanks for the info.

No, this will not work.

Virtual machines present an emulated set of hardware to the guest OS (in this case, pretending to be an ES1371) and then use the underlying OS (Mac OSX with the OSX Cirrus Logic driver) to interface with the real hardware. The guest OS (Windows) sees the set of emulated hardware devices of the "virtual machine", not the real hardware of the real machine. There are no volume issues in VMware because it uses the underlying OSX Cirrus Logic driver to control the audio chip.

Under VMware, Windows sees the virtual ES1371 device, so Windows uses a driver for ES1371. Under Boot Camp, Windows sees the real CS4206A device, so you'll need a Windows CS4206A driver.

this guys right. emulated hardware drivers won't work with regular hard ware drivers
 
Thank you very much, henry128 and cmosq! I now have usable volume under Windows 7 32 on my MBP 13". Nice work.
 
Hi everyone.

I'm a user from Singapore, and it's almost impossible for us here to download from Rapidshare since the whole country seems to share an external IP address. Is it possible for a good samaritan to upload the fixes to somewhere more convenient for the rest of the world to download?

Unfortunately, anything along the lines of Rapidshare (e.g. Megaupload) is pretty much out, so I'm not sure what other options there are.

cheej:

If you can find a service that works from your location, I'd be happy to u/l them for you. The files are only ~600KB each. Or alternatively, post a throw-away email address and I'll send them to you.
