what's strange here is that audio is working properly only with USB booting.

I can boot from the HD bootloader but then audio is not working.I tried everything but at this time no go with hd booting.

 

I used chameleon enoch r2403 for USB key. tried to reproduce everything on HD but there's no way to load properly.

Guys,

 

i have more of a knowledge gathering question :) . I have the same card ALC1200(ALC888) and it's been working fine in Mavericks using the kext from ##### (ALC888 Legacy v100202). Once i upgraded to Yosemite that kext would not longer work.  I have never used DSDT before so had to figure it out and it finally works (used instructions from post #550).  As i am learning how to work with DSDTs here are my questions:

 

1) any idea why ##### kext for ALC888 stopped working in Yosemite

2) if the purpose of DSDT is to tell OSX how to interact with hardware, why did i have to install AppleHDA.kext. I thought with DSDT don't have to mess with kext anymore

3) In post #550 Manu0600 provides two files: HDEF and DTGP.  The very first post only provides HDEF file.  Is there a need for DTGP file ?

 

Thank you very much for your time

Same problem for me. Fully edited DSDT for Mavericks.

Sound worked with patched AppleHDA und HDAEnabler from Mateo.

 

But now in Yosemite no sound!

Board is P5QSE/R

You can find ALC1200 on:
Asus P5Q tested ok
etc. etc. etc.
MSI P43 tested ok
GA-945GCMX-S2 tested ok

 
Anyone test the ASUS M4A79T?
By manual it has a ALC1200. Under windows it is shown with Ven.ID: 10EC Dev.Id: 0888
So.... Is it a ALC1200 and i've to follow this guide, or it is an ALC888 and i have to follow another one?
i'm newbie and it's a little tricky for me to understand.
Thank you

The main difference is that ALCinjector is not needed, so you're running a clean vanilla AppleHDA kext from latest 10.5.6 update just modded for ALC1200.
On the other hand this driver has potential to be fully working. Line-in could be on the to-do-list, I've not so many time to spend, but I'll try.

Hello finally i get audio to work on my P6TSE, but only Stereo while i have 5.1

 

I am searching solution for three days, I understand that I have to modify my layout-id but how and where??

 

I also tried to edit my layout-id block (inside HDEF) from this:

 

"layout-id", 
 Buffer (0x04)
{
    0x0C, 0x00, 0x00, 0x00
},

 

 

to this:

 

 

"layout-id", 

 Buffer (0x04)
{
    0x07, 0x00, 0x00, 0x00
},

 

According to:

 

 

 Layout_ID 3 = ​​For Laptop's.

                      Layout_ID 5 = ​​3 ports supported (Pink, Green, Blue) 

                      Layout_ID 7 = 5/6 ports supported (Grey, Black, Laranja, Pink, Green, Blue) 

                      Layout_ID 9 = 5/6 ports supported (Grey, Black, Laranja, Pink, Green, Blue, CodecAddress: 2)

 

After reboot no audio

 

In first post i don't well understand the usage of this:

 

 

 

these are the xmls needed for our ALC1200 to work right
zip.gif  layout_and_platforms.zip   8.36KB   1813 downloads  

 

Can someone explain me where i am wrong?? And why my "layout-id = 12" ??
