Alc883 codec dump

Let me start by saying that this tutorial is far from complete, but I'm a very busy person Mozilla Application Developer and thus all this has to be done in spare time so yeah The good news is that this old geezer is writing a new article about audio stuff on the hackintosh, and thus we might get there one day soon.

What this is not: Please note that this is not a freeway to audio heaven. And no I am not going to fix your audio kexts. It's all up to you I simply won't have the time for it since I'm also a father of four children Hey, I am already writing this tutorial, remember? The first thing you need is either a Windows or Linux codec dump. And you can generate it on Linux with:. I personally used my Ubuntu 8.

I later compared the codec dump with Ubuntu 9. Don't have Linux, yet? Simply get the Ubuntu LiveCD here instructions included , but you might as well try one of the other Linux distributions. Probably just a way for Apple to say: " We have 10 million developers world wide ". Just because people need Xcode IDE and thus have to become a registered developer. Let's get started. First download the attached codec scroll down to Files and open it with something like TextEdit or whatever tools you prefer to use.

We'll be using this codec throughout this tutorial, as an example, but you should first compare it with your own codec look for similarities. Now let's have a look at the codec here, starting with the following lines:. So what exactly are we looking for? Good question. It might not be 0 but for example 1 or 2. And you'll be using this value in the following paragraphs so yeah, it is pretty important.

The second value is The Pin Default a bit register in the Pin Complex Widget is used by software as an aid in determining the configuration of jacks and devices attached to the codec. We also need to keep an eye on the Sequence , simply because it can only be 0 on real Mac's. Note the right-to-left or host-byte-order , which might look strange at first for non-developers, but that's how it works.

Follow the jump to the Intel HDA specification for a complete description starting at page which I tell you is a must read. Note: the 71x part in this group is the Verb ID which is used by the software to identify verbs. And there's no word about 71b in the Intel HDA specifications so we'll simply ignore it here.

Now repeat this procedure for all other snippets containing: Node and Pin Default. The above value for Sequence can only be 0 on a Mac and thus we simply need to change it, or things won't work properly. And here's the patched group:. Let's do the rest, but this time even more information ls removed, and that is why we start with the following color table from the Intel HDA Specifications Table :. Putting the whole bunch together gives us the ConfigData we need for Info.

Converting NodeID's. Our First Result. Please note that there are two kind of data sets, of which one make System Profiler show the info, and another to make your sound actually work and show up under Output and Input in System Preferences sound. Please keep in mind that having something in System Profiler, under Audio Built-in doesn't necessarily mean that your sound will actually work, but merely that it can find something to show!

It is however a start, and used as an example only here. Installing Software. The next thing you might need to do is to install Codecgraph and Graphviz. This to generate a graphical presentation Scalable Vector Graphics of your codec. Please note that you don't necessarily need to do this, at least not when your codec dump is listed under the " Known codecs " section of the first link.

But here's a little how for us Linux users:. You might want to scroll down to Files and have a look at the attached SVG files. Note: Continue reading "The next step - making connections" when you already have a codec dump! Making connections.

But more about plist files later. I'll remove everything but the lines we're interested in:. No asterisk this time. No, we're gonna have to figure that out ourself, which is pretty easy because we know what kind of connection we're working on - being our output device. Yep, that's the one we're looking for.

This is the first one:. Now, let's do another one. Again, I'll remove everything but the interesting lines:. That's the Audio Mixer we're looking for. And here's the connection list:. That was the second one. Here's the outcome:.

Read this: Analog output devices can be tracked from the source, being the Pin Complex to their corresponding Audio Mixer. Digital devices however don't need the latter and thus these are a little less complex to setup. Input devices are a different kind of beast, because you need to follow the opposite direction, being from the connector towards the corresponding Audio Mixer and Pin Complex.

Dead end. Back to the codec dump. That's what we need. Both have connections to either Audio Mixer so just pick one. Leading to the following input devices:. Putting it together. Let's start with kext files. Nothing magic; though they might look a bit strange at first. In fact that way things are less messy, and OS upgrades are less likely to break your installation.

It also depends on the installed version of OS X, and how you want to fix your audio when needed because injecting data with legacy kexts is not the same thing as injecting data from your modified dsdt. Note: DSDT hacking is not the holy grail and is probably a bit too difficult for many people no offense so only take this route when you know what you are doing! Now back to hacking. The most importantly two are just property files:. People who inject data with a modified dsdt.

If I'm mistaken, please point me in the right direction. If we set it too much the sound maybe have too much bass or too much "deep". The best way right now is just use the legacy kext compatible with SL which available in this forum. I forgot who made it but it works just fine.

If you want to learn more, there is a couple documentation about Intel HDA sound which you might want to read. Another problem is that I have mute-only amplifier on a node connecting to Microphone, and I cannot find right settings to enable this node in AppleHDA. I can send direct verb command to the node, but it will be reset after Sleep. I just noticed that you post additional info here and here which I will copy and paste into my reply before it is gone since you post in the wrong place :.

And because of this missing info I can now tell you at least something. That you need to patch AppleHDA in order to get it going below the terminal command :. But you'll still need to complete the pin configuration with the info found in the first post. Additionally you may want to read my hunt for sound here posts 3, 4 and 5 only but please, please do NOT comment there about your ALC problems.

Is it possible to do it manually or is there a software for converting it? It's told often, that this ALC should be working out-of-the-box but it doesn't with the latest releases of Snow Leopard. What I did now: dumped the codec in Ubuntu dump attached below , extracted the PinConfig in Windows7, converted with the online converter you suggested, and saved the output. Maybe you have any clue how to continue with this chip.

I attached all output I have.
