Did it work tarasis?

Sorry kids got in the road and forgot. No didn't do squat, but to be expected as the new 13" MBP's use Cirrus Logic HW and they don't appear to provide public drivers. They basically point you to the HW manufacturer, which means till Apple release a new version of Bootcamp drivers we are stuff.

Incredibly surprised that Apple would ship Bootcamp drivers this borked, you'd have thought they might have checked.
 
petty mac vs ms bs

so ridiculous, apple are just doing it slow and tedious to make people side with the osx... really frustrating, and if someone told me that they were playing this immature corporate game, i for one would not have paid the stupid price i did to get a macbook pro, thinking that i was the winner get both operating systems in one laptop...
GROW UP APPLE, YOU ALREADY OVER CHARGE YOUR CUSTOMERS ENOUGH, YOU'VE TAKEN HAVE ENOUGH MONEY FROM THE VERY PEOPLE WHO KEEP YOU AFLOAT, NOW GIVE US THE BOOT CAMP WE WERE PROMISED AND THAT WE KNOW YOU KNOW HOW TO FIX!!

p.s: post it up people if the dooshbags do fix the audio problems in the near future...
 
SOLUTION for Windows 7

Hi all,
I am running Windows 7 Build 7100 64bit and none of the descibed solutions did help so far. The Realtek drivers install but do not produce sound anyway.

Here is my solution to get a higher output on the MacBookPro 13" Unibody.

You have to use the Bootcamp Drivers for the Cirrus Logic device.
..\Boot Camp\Drivers\Cirrus\ unpack the CirrusAudioVista64.exe or 32bit version to a seperate folder.

inside the folder there is the file "cs420x.inf".
Inside this file there are amplifier capability overrides defined, like max. +0db Output...

You can edit these settings with a simple text editor, and finally reinstall the driver.

I will include my modified inf file for 64bit windows.
Please try to modifie the 32bit version on your own - I just copied existing lines from different places within the inf file - so I did not have to bother with the dword values in deep - but I think one can even better modifiy them with knowing what they mean !!

Have luck with that one.

Once again, if you modify the value, you have to uninstall previous devices within the device manager including deleting the older files in the system directories. Finally you have to point the driver installation to the exact point of the inf file.

Please change the ending of the file from .inf.txt back to .inf only

ChristianZ,

Does this fix the problem where the right speaker is operating at only half the volume of the left speaker?

How hard can it be to release drivers that work? This will be the last time I buy an Apple product so soon after it is released.

:mad:
 
Yes, it should fix this problem.

As far as I can tell the inf file had only one line (right or left) with reduced gain. That might be the reason for this behaviour.

Hope it helps.

Interestingly the XP version of the driver (clhdaud.inf) doesn't appear to have all the settings for the amp like vista does.

Yet to try copying them over from the Vista ini file but I wouldn't have hope as the Reg key setup is quite different.
 
I tried making a thread about this earlier and didn't get any replies. It's definitely a real issue, and many people seem to be downgrading to XP for gaming/anything that uses audio.

I tried reinstalling the latest realtek hd drivers to no avail. Never tried to find cirrus logic drivers though. Hopefully a fix will be figured out eventually - Windows 7 is free for me, it would suck to have to put down money for XP!

Im using xp and i have EXACTLY the same issue
 
Im using xp and i have EXACTLY the same issue
I'm using XP Home under Bootcamp and I have the same problem: very low audio in loudspeakers, but the audio volume in headphones is ok. No problem in MAc OS.
I have a new macbook pro 2,66 (6 days of life....) :confused:
I just phoned Apple CAre and after 10 minutes the girl said to me that I was the first with this kind of problem and told me to ask Microsoft!!!!!
This is my first experience with Apple but is starting quite badly...:cool:
Marco
 
Sorry to hear of your troubles marco. Apple are definitely responsible for supporting their Boot Camp drivers under Windows.

This is the last Apple product I will buy until Apple demonstrate some sort of commitment to provide decent drivers for Boot Camp. It seems to me they paid some kid $15 to write these drivers. Did it even occur to anybody at Apple to test Boot Camp on the new Macbook Pros?

Very unimpressed. :mad:
 
I have also this problem: My RAM is 4 GB but only 2,7 GB is noticed. And the webcam gives an image that is only 160x120 pixels!!!
 
Oh wow you're a genius! this worked perfectly I can finallly play some music!

Good job! :D:D:apple:

same prob...low screen/keybd keys too?

Just experience this problem myself, 13" MBP using internal speakers.

Digging into the mixer it appears the that audio on the right speaker is too low.

If you go to the Speaker Properties -> Advanced and select Test you will hear the left speaker really loudly and the Right speaker quietly (like half the volume). This is despite the Levels -> Balance showing both L, R, C & sub at full.

Installed XP Pro SP2 on first gen uMBP 13" 4 GB.

Audio vol from left and right speakers appear same to me using Realtek Audio mixer to isolate the channels. I do note that the bass comes out of the right and high end out of the left speakers, giving the impression that the left speaker is maybe lower.

Youtube volume is ok, but can be low too on some videos, e.g. Black Eye Peas Boom Boom Pow.

But some audio sources can be normal volume too, e.g. NPR radio.

Mic and webcam works fine.

Systemin info says 4 GB memory, but task manager says 2.7 GB. Dunno if I can really use the full 4 GB.

I've also noticed that the screen and keybd brightness is not as high in XP versus OS X. Anyone else notice? (should just search MR forums)

Can't try the Windows 7 fix suggested by ChristianZ cuz I need XP for work!

If someone finds an XP fix, pls post!

I still have the problem... I tried to modify the cs420x.inf file but i don't know which lines to change and how to use that file to reinstall the driver...

In my MBP the system installs the audio drivers and when I play a song in Windows 7 it looks like if the sound works fine... but I can hear nothing...

Somebody has find other easier solution? Thanks a lot...

You say I need to delete the older files in the system dirs. What exact files are you referring to? I uninstall the sound device within device manager and install my new drivers via the .exe and reboot and no audio at all. It treats it like there's audio but there is nothing. I have modified the 32 bit version using the same exact values you have used in yours. Maybe this is because I'm running Vista and not 7.

Has anyone gotten it fixed on Vista? .....specifically 32 bit?

Otherwise I may just have to upgrade to the Win7 RTM.

Hi, it's the same with Windows 7. I have the same problem, but I don't know how to modify that file.

Are you using 64 bit or 32 bit? That guys is using 64 bit and solved the probelm so I'll just go that route if it's worked for two people thus far.

"Thanks to cmosquera for this fix.

This will fix the volume on the computer. If you also did the audio enhancement described above undo it.

1. Create a folder on the root of your c:\ drive, call it "CirrusDriverFix".

2. Install 7-Zip in your Vista or W7.

3. Put the Mac OSX Install DVD that came bundled with your Mid 2009 MBP in your DVD drive then right click on the BootCamp\Drivers\Cirrus\CirrusAudioVistaxx.exe (xx=32 for 32 bit and 64 for 64-bit) file and choose "7-Zip > Extract Files..." Enter c:\CirrusDriverFix to extract the files.

4. Once the files have been extracted go to the c:\CirrusDriverFix folder and delete the original cs420x.inf file and replace it with the one attached to http://att.macrumors.com/attachment.php?attachmentid=182216&d=1247310061 make sure the you rename it to cs420x.inf

5. Go into your device manager, right click on the Cirrus Logic under "Sound, video and game controllers" then choose Uninstall and make sure to check the box "Delete the driver software for this device."

6. Click on Start > type "cmd" then right click on the cmd.exe that shows up and click "Run as administrator".

7. type in CD "\CirrusDriverFix"

8. type in dpinst /F and then go through the install, it should "force" the install.

9. Enjoy your sound.

10. Thank ChristianZ and everyone else except Apple, Cirrus Logic, and Soft Reset "

"You may be experiencing the same problem I had. If so, this will help. In your device manager you say everything looks good, but check again, is "sound" device listed at all? When I performed the above steps my computer didn't see that I had speakers at all. In windows 7 when I clicked on the speaker in the lower left on the task bar Windows automatically tried to detect and fix problem. In doing so Windows installed a generic windows audio driver, which showed up in the device manager. I ran the command prompt again and reinstalled the new audio cirrus audio driver and everything worked perfectly."
 
Installed the realtek drivers in xp and windows 7. They changed nothing, as I expected. I am extremely angry how Apple doesn't test their newest hardware with all bootcamp. I'm considering returning my computer until they get all these issues sorted out.

Ummm...Windows 7 is currently a Release Candidate, once the actual release occurs in October then Apple will release an update to support it. They have no obligation to support Windows at all, but do it for the ease of use, and certainly have no obligation to support pre-release software like the current W7 build.

What are you talking about. For one, I explicitly said that there were problems under XP, which you know has been out for a decade, AS WELL AS windows 7, which uses the same driver architecture as Vista, which you know has been out for a couple of years. That's not the point though. The point is that Apple states that with their bootcamp software you can run windows natively on a mac. WHICH MEANS that, yes, they do have every obligation to support Windows. Apple isn't doing you a charity by supporting Windows, they're doing it as a feature of their computers --->> AS A WAY TO MAKE MONEY. Really, if you just came here to complain about a complaint I had then you should have just left.
