This solution works for me, i got a Sony Vaio VGN-C140F/B with Core 2 Duo 1.66GHz, so i have the realtek high definition audio sound card in windows Xp works excellent, so when i install mac os x 10.4.6HOTiSO didn't work, so i search for almost all the forum to get a solution so i found it, so this solution works for me so let's go:

You must to check this things before you do something:

1. Your codec is the Realtek ALC262 (vendor id=10EC ; device id=0262).
2. The controller chip you will have to look up. Go into Windows' Device Manager. In Device Manager, go to "System devices". Find "Microsoft UAA Bus Driver For High Definition Audio"and get Properties. Then click the Details tab and get the vendor and device ids, you must have this (vendor id=8086, device id=27D8).
3. When you got this information change to mac os x.
4. First, Backup the AppleHDA.kext, in a location wherever you want. You find it on /System/Library/Extensions/AppleHDA.kext
5. Find the kext AppleAzaliaAudio.kext and edit it:

In Terminal, type:

cd /System/Library/Extensions
sudo pico AppleAzaliaAudio.kext/Contents/Info.plist

then search for IOHDAudioCodecVendorID, when you find it

Find:
<key>IOHDAudioCodecVendorID</key>
<string>0x10ec0880</string>
Change <string>0x10ec0880</string> -- to -- <string>0x10ec0262</string>

For exit pico: press Ctrl + O to save and then Ctrl + X to exit.

6. In Terminal, type:

sudo pico AppleAzaliaAudio.kext/Contents/PlugIns/AppleAzaliaController.kext/Contents/Info.plist

Search for IOPCIPrimaryMatch.

Find:
<key>IOPCIPrimaryMatch</key>
<string>0xNNNN8086</string> (where NNNN are any 4 characters)
Change <string>0xNNNN8086</string> -- to -- <string>0x27d88086</string>
For exit pico: press Ctrl + O to save and then Ctrl + X to exit

7. Repair Perimissions using the disk utility in Utilies in the Finder or typing in terminal: sudo diskutil repairpermissions /

8. In Terminal type: sudo chown -R root:wheel AppleAzaliaAudio.kext

9. In Terminal type: sudo chmod -R 755 AppleAzaliaAudio.kext

10. In Termina type: cd /System/Library
sudo rm -rf Extensions.mkext Extensions.kextcache


11. Then if you do this well, reboot and you have SOUND!!!!!!!!!!!!


Of course works for me, please feedback and let me know anything about the solution.

Hi Camilo, the only way you could see if it work, is trying to do the guide, so i don't now if the line in works, because in my laptop when i try to plug in the headphones it didn't work, so i don't know why, and i'm try to fix but with no succes, i think the kext is not design for that sound card, and only was a compatible way to get sound with that kext, so im working on it, if i have news i let you know, so thanks for the question bye bye.

Greetings

with the same controller and audio card on a fujitsu laptop I still have problems.

I've followed the guide and now i can see a device on the output tab, but still no sound from speakers or headphone.

Any suggestion ?

Thanks

Hi macosse, did you delete the AppleHDA.kext? and did you repair Permissions?, if you done this, maybe you speakers don't work, because in some cases you have configured the sound but, the speakers don't work is a kind of bug, presented in some laptops. Give me more details, of how did you do, step by step?

Greetings.

Hey ayrus02, try first deleting the AppleHDA.kext (I recommend you to make a backup first, just put it in another folder, then delete it), do the guide again Im prettey sure that will work correctly, remember to deleate AppelHDA.kext, if you dont do this it will not work, if you do it correctly you will have output sound on speakers or headphone (it seems that is just one of then no both, I mean you can have onle on speakers or only on headphone), and you will not get the mic in, but hey!! its a progress, theres some drivers patch for this alc262 cards, but it didnt work for me, Im still waiting for it, ciao.

Guys,

I have to say excellent work I now have sound working on my Samsung Q1U! Theres a bit of a sync issue when playing with video but listening to music from itunes works. If I can get that issue resolved i would be in heaven. Finally, does anyone know of a touch screen calibration tool for OSX?

Yes Alfred, I've done everything exactly as you explained. I have a Fujitsu lifebook c1040 and I've now tried with a fresh install (xxx 10.4.10) but still the same result. I've also tried with the easy fix published here but nothing. I'msure to have the same controller and the same Realtek chip of your guide and I've done exactly what you wrote. I do have now an output device in the audio system preferences, but still not working. It's a pity!!Thank you very much for you interest and for your nice howto, though.

This methods works great on my Sony C1Z laptop with ALC262 audio. Took me a while to figure out that I needed to remove the AppleHDA.kext from the extensions folder, but after that final step, I have built in audio working just fine... (no headphone output as expected...)

Can I suggest the first post is edited to say that the AppleHDA should be backed up AND REMOVED from the extensions folder? I'm sure that would help future ALC262 owners.

Big thanks for to the original poster for this fix...

I've found a user with the same card (alc262) in a similar laptop, that was able to get it working with azalia audio but only with a 10.4.9 release.
So I've tried myself but still nothing was working. It's really strange.
I've then tried with a different approach; 10.4.10 fresh install and taruga's test kext for alc262 (so no need for azalia and with a patched AppleHDA and ALCInject).
Now headphones are working but not internal speakers. With taruga's test1 kext only headphones are shown in system preferences; with both test2 and test3 also internal speakers are shown in system preferences but only headphones are working .
Hope this will help someone the same problem.
I will keep tring to get internal speakers working.
Thanks again to Alfred for sharing his solution.



Specs:
Lifebook C1040
XXX 10.4.10
ALC262 (only headphones with taruga's method )
Marvell Gigabit Ethernet (working)
Intel 945GM (working)
Intel 3945wireless (will see later...)

I have this audio card, but have not probed the problem down to the id.etc...

but wanted to let you guys know about a great little device I've had for a awhile:

Behringer U-Control UCA202


It's plug'n'play with no drivers [sometimes I've noticed it needs to be plugged in when you power it on for the first time, but then it seems to recognize it from then on after it loads the drivers info into cache].

Optical in and out, along with RCAs. Headphone pre-amp. Bus powered.

For less then $30 dollars shipped, its well worth it.

Does this patch work with all brands of laptop or is it just for your laptop with similar hardware/vendor id? I have a everex brand laptop with alc262 sound card.
