AD1984 used in Thinkpad X61 and L61 computers, let's sort this one out Options

I believe that was the patch that I had installed (which does exactly what Popophobia's post says). The odd thing is it isn't giving me that symptom at all anymore. As for the other people on Taruga's wiki-- that was me. I posted once when it worked, then said that 10.5.3 broke that symptom from happening.

I'm tearing my hair out trying to replicate it-- I have absolutely no clue as to why it isn't happening for me again.

There was another thread on here where somebody (I believe his name was Agent) mentioned their audio worked with a Kalyway install, but not with an iAtkos install at all.

I'm using your kext file that you posted here (running off a clean and new iAtkos v2.0 installation) and am not getting that symptom whatsoever. AFAIK Kalyway comes with pre-patched audio, or gives options to run some sorts of audio patches at install whereas iAtkos doesn't. Please disregard my posts on Taruga's wiki-- although I experienced the symptom I really don't recall which installation I was on (it may have been an iAtkos installed over a Kalyway 10.5.1 installation). I had been working late nights and installed a crapload of patches.

Someone reported sound on R61 - another AD1984 working with AppleAzalia...

I'm PMing him to get more details..

[jacob019]

this azalia business is exciting, I had given up on that route. Please keep up the research. I'll give it a close look over the weekend and see if I can't help.

Tried a Kalyway 10.5.1 install, but couldn't get anything working right at all.

Is there a difference between running GUID and MBR at all?

not really, you can't run a vanilla kernel under MBR mode, but in my experience it works better, especially for multibooting.

[popophobia]

Ok, here is the exciting bit:

I installed the OS X using both iAtkos 2.0 and Kalyway 10.5.2 on a separate HDD (2 installs on 2 partitions). Here are the results:

1. Kalyway: No wireles, no volume controller on first boot. However, on my second boot, HDA Output was added to SysPref>Sound>Output. The short burst of sound occurs every disconnecting AC. Wireless works in a blink of an eye after copy the kext from iAtkos (Atheros 5005g hack I think). No reboot required.

2. iAtkos: better integration, everything is there after the first boot. Same, short burst is fully replicated and occurs everytime.


One side note: when I use the dock and remove them without turning off the laptop, there is some kind of sound at the speaker. This leads me to believe that the problem is not in the codec, but in the power of the small speaker alone. I'm looking to do some Azilia mod (it was not applied to any of the above installations). thinkpad.com forums have some nice info about this. I might try that.

I think if you can get a blank hdd (or a partition to spare), install these new version and give it a spin. Totally worthed. I was too worry about having to do everything from scratch. It's not even that bad.

[mulletman13]

Popophobia -- were these under GUID or MBR? I'm not getting the symptom under any conditions with either (under MBR).

jacob -- I was not aware that vanilla was unable to run on MBR? Installing via iAtkos I installed all stock files (Vanilla 9.2.2 and even the stock AppleACPIPlatform.kext) and all ran completely fine.

Anyways I'm done with reinstalling everything just to replicate it. Now that we have popophobia getting the same result consistantly that's excellent.

[popophobia]

Make sure you have the volume slider. Without it, no sound will be produced, pulling the cord or not.

I installed the default for Kalyway DVD, audio section (includes the Intel HDA and a few other i think).

Curiously, the sound card is identified as Intel HDA with device ID. I'm still on Kalyway 10.5.2.

I installed with GUID, but either case, it does not affect the sound nor the driver. Just the way it boot up. My first installation was MBR.

Hi guys,I can still reproduce the short burst of music when plug/unplug the AC adapter.

Basically Azalia patch moved ALCInject.kext, AppleHDA.kext into AzaliaBackup and create AppleAzaliaAudio.kext in system/library/extensions folder.
I'll try to find the patch again.

But I'm sure it's not the only way to get the short burst of sound. If you check taruga site, seems like there are 2-3 users experienced the same thing without azalia patch. I'll try to install iAtkos 2.0 and see if I can get the same symptom.

Anyway, my system still has the symptom, let me know what kext you would want to look at.

I went ahead and attach the ioreg output and AppleAzaliaAudio.kext. Hopefully it'll have some use.

In ioreg there are a few entries linked back to appleazalia codecs. I'm sure you can get something out of it.

Hey popophobia,

Your ioreg is cut off - can you re-run like this and post the output?

CODE

ioreg -w0 -lif > ~/ioreg.txt

[popophobia]

Hmm sorry about that

Here it is again.

[T u r b o]

Hey popophobia,

You can take down the ioreg link, I don't need it anymore. I was finally able to reproduce the burst-of-sound issue, and I'm pretty sure people who are no longer able to reproduce this are seeing the result of a race-condition on startup.

See my site http://0xfeedbeef.com/osx86/ for details.

I need to do some more work but a patch should be available soon.

Hey Turbo,

Glad to hear that you got it working! I've attempted to load the kext's as per the information on your website, but each time I do that, the kexts load but disable the volume buttons and do not reproduce that symptom.

Additionally I saw you got your backlight working on your ThinkPad-- do you think you could post that solution, or throw it up somewhere? I'm sure a LOT of us ThinkPad users would love to have it!

Thanks!

Guys the Dell Optiplex 755 also makes use of the AD1984 so do you think if you got this working for the thinkpad chipset that it will work on the Dell Optiplex 755 too???

Thanks for all your hard work keep at it.

Thanks. That's great news. I'll be looking forward to that. Finally something is moving in the right direction

Also, as mulletman said, it would be great if you can share some of your driver for X61. We (me an a bunch other fellows here at the little x61 wiki) would be thankful for that.

So does anyone know if this patch would work on a Dell Optiplex 755 which also uses AD1984?

Here is a screenshot I took in OSX 10.5.3 with device ids.

[mulletman13]

Worked PERFECTLY for me! Thank you so much Turbo-- once my ebay auctions end next week i'll send something your way!

Thank you SO MUCH!

PS: Also did your x3100 backlight fix work? Do you have any plans of releasing that to the ThinkPad osx86 community? Thanks!

[Riotz]

Exciting news guys. I tried the kext on my Optiplex 755 but was not able to get it working. I was wondering if I am doing something wrong. I used Kext Helper to try to get it installed. If there is a different way of getting it in there please let me know.

[mulletman13]

Riotz -- this patch was meant for the way Lenovo machines handle the 1984-- which is different than the way your Dell does unfortunately

[zakfontaine]

Hey,
Tried this on my T61 via kext helper, and it didn't work. Exciting news though!
