Hello,

 

ML is insalled and updated to 10.8.4 but I have no sound.

 

I did a codec dump and my Codec is VIA VT1802..

 

I found some code which will apparently get me to the following status:

 

Int. Spk, Headphone, Int mic working, Lineout unknown yet..

 

https://github.com/maxfierke/Lemu4-Hackintosh-Config/commit/39f8deca09af7d1403d727a5419968598e15ea77

 

https://github.com/m...s/Platforms.xml

 

https://github.com/m...es/layout12.xml

 

I know its to do with patching the applehda, but I'm clueless as to how to actually do what I need to do using this code...

 

Can anyone help please?

 

Thanks

Hi,

 

Thanks, I tried voodoohda, didn't work...showed up in mysystem prefences but no actual sound...

 

The guy reckons he has patched AppleHDA for this codec and got it most/all of it working..

I now have the following files in relation to it:

 

Configdata.txt

pinconfigurations.txt

verbit_vt1802.txt

verbitdebug.txt

vt1802_dec.txt

vt1802_dec.txt.svg

vt1802.txt

vt1802.txt.svg

 

And a folder called AppleHDA_Patch_files inside of which is:

 

layout12.xml

platforms.xml

 

I read that voodoo is not very good (at least on this machine), but i'd use it if it was working, but it isn't..Hopefully I'll hear back from the guy who did the patch work on how to use this stuff...I think all of the work real work is pretty much done, just don't know any thing about this stuff..

Hi, there is much info about AppleHDA patching in the sound section of this forum. Basically you need to:

- do a binary patch for AppleHDA

- edit AppleHDAHardwareConfigDriver's Info.plist and insert a new section for your audio chip together with the PinConfiguration array

- replace layout12.xml and Platforms.xml in Resources folder

- inject layout-id 12 either with an enabler kext or with a DSDT modification

 

I can try to help you with the binary patch, the rest is documented well.

Hey,

 

Sorry for the delay, had to go away. Yes that would be brilliant if you could help..I have a feeling that I have all the files and txt I need to paste but I don't know how/where to put everything.I have a feeling the binary patch has already been done and saved, and is the folder I have ready to be copied or something..but I don't know, so yes If you could help me with that I will start reading the sound section see I can figure out what to do with all the files and code I already have...

 

Thanks

Most audio chips are masked as AD1984 which is supported by Apple. The device id of AD1984 is 0x11D41984. VT1802 (yours) is: 0x11068446.

Open the AppleHDA binary in a hex editor and replace: 8419D411 with 46840611 - you should find two occurrences.

 

For the rest of the steps open AppleHDA.kext, look through the contents and you should find the things easily. Otherwise just ask.

You need to add the EAPD for the devices with them or they won't work.

 

You'd want to use this codec verb instead:

 

02471c10 02471d01 02471e17 02471f90 02470c03 02571c20 02571d40 02571e21 02571f02 02570c02 02971c30 02971d01 02971ea0 02971f90 02b71c40 02b71d90 02b71e81002b71f01 02470c03 02570c02

 

For your first EAPD node (0x24), you need 02470c03 where 70c is for the EAPD and the 03 is for the data

For the second one (0x25), you need 02570c02

No need to do all that complicated hex editing stuff, just use this kext and all audio including mic and headphones will work.  All works fine for me.  http://www.osx86.net...2-ml-for-via-vt

 

It says its for mountain lion but it works fine for mavericks.  I got the Via VT1802.
