Hi there,
I have a G74SX laptop, running MLion, which needs some fixes. About audio, I tryed voodooHDA.kext but it has several issues. So I am trying a patched appleHDA.kext for alc269, which seems to work on g73sw, as ralf_64 testified in this post: http://www.tonymacx86.com/mountain-lion-laptop-support/61769-g73sw-g74sw-gm-install-coming-soon.html
Unfortunately it doesn't work that good on my model, which should be almost identical apart of graphic card. Mic internal and external works perfectly, headphones too, but no way to let laptop speaker work.
I made some research, and I found this post: http://legacy.tonymacx86.com/viewtopic.php?f=170&t=58422
In here, MlyDinEsH explains how he reached it to work editing applehda.kext. Reading this post, I started to think that problem could be a different disposition of jacks used by my laptop, so that internal speakers are addressed somewhere, but should target another address. In this post MlyDinEsH explains also this:
1) How to understand, from this codec dump, the jacks which are used in my laptop
2) How to translate this values from things like "14(int speaker)" to something like "01471c40 01471d01 01471e13 01471f99"
I tryed to find a clear guide on internet without success, so if someone could help, I'd really appreciate.
Thanks in advance

Now, If I understood, I have to make a codec dump file from linux (which I did). But I don't understand 2 things:MlyDinEsH said:edit the Item "CodecID" to 283902569,
"ConfigData" to "<01471c40 01471d01 01471e13 01471f99 01871c20 01871d10 01871e81 01871f04 01971c10 01971d01 01971ea0 01971f99 02171c50 02171d10 02171e21 02171f04 01470c02>"
[ Here, in this config data the nodes for the jacks are 14(Int Speaker), 18(Ext Mic), 19(Int Mic) and 21(Ext headphone), so edit according to yours]
