No Audio with Macbook Pro

I get no audio within windows and when I bring up an Volume control it says "There are no active Mixer Devices available."

I have tried updating the unknown PCI device automatically and by pointing to the drivers on the leopard CD. It couldnt find them. I also tried pointing to the realteck drivers off thier site but it wouldn't take it as realted to the hardware.

Installed thoes drivers off the realtech site.

I seem to be having a simular problem as many but thier solutions were not successfull.

makbook pro, Mac OS X (10.5.1)

Have you ran the Realtek driver installer from the Leopard disk and rebooted BEFORE you've tried this ?

That's what I did.

Yes, and the same "hardware update wizard" pops up.

This problem is not unique to Macbook. The Realtek or Sigmatek drivers will not allow me access to outboard pro-audio gear by M-Audio and/or Tascam through firewire ports. *Bootcamp is not ready for prime time.* What is frustrating is that this worked on my macbook and bootcamp public beta.

I have the same problem with my MBP. I think the issue lies within which version of Windows you have installed. The only drivers I see available are for sp1 and sp2. I don't think there is a Realtek sp3 driver out yet. Just for clarification, are you guys also using sp3?

Jan 31, 2008 6:22 PM in response to Devo Smashing

i am experiencing the same problem with the Sigmatel/RealTek audio drivers on a MBP (2007), and i AM trying to do so on on an XP-SP3 beta (3282), but i doubt all these people are doing like-wise?

can a few of you confirm that you're using XP-SP2, not SP3?

hey Everyone, Enio (over in this thread: http://discussions.apple.com/thread.jspa?threadID=1368671&tstart=0 ) has discovered a fix for this problem that's worked for at least 2 of us so far.

this fix involves running a Windows patch file that's inside the SigmaTel drivers on the BootCamp drivers CD (or Leopard CD). or you can download it from Enio's .Mac page, in case you don't have WinRAR/etc.

I got an error when the patch completed & it said i needed to reboot, but i got Windows' sounds on both the shut-down & then on the reboot, all seems fine now.

Yes, in fact I am using Sp3, and had completely disregarded that as a factor for it not working.
As for the solution you have posted Enio gave you, I opened the kb835221.exe from the Leopard Disc, it seemed to complete the installation and I rebooted. After this, the audio device isn't recognized yet, and the PCI driver exclamation mark (meaning it is not installed) is still there.
Did this problem with the PCI driver happen to you?
If not, is there any way I can fix it?

Well I am running SP2 and seeing as I managed to install by prodding the yellow ! after installing the Realtek driver on disk perhaps you SP3 folk will have same luck after installing SP3 friendly driver.

I downloaded an appropriate driver from the address below to use with my Mac Pro. Don't know if it will help but you could try it:

I'm using XP with Service pack 2 (SP2) on my Mac Pro and it's now working fine. I downloaded the latest Realtek HD Driver from Realtek Website. Then I played around with the realtek settings via ControlPanel>RealTekHDSoundEffectsManager under the audio I/O tab. I don't know if it's different with the MBP, but I hope this helps. the download addres for the driver is:

Now that's a good sound, Windows user approach to solving this problem. Thanks for the info, that will com in handy when I eventually purchase a MBP

I found out this link that provides UAA drivers and made sound work for me on my macbook with SP3 RC2 on it : http://www.techarp.com/showarticle.aspx?artno=490

(see the driver at the bottom of the page : need 7zip ton uncompress)

I hope that helps 🙂
