Mountain Lion HDMI Audio

[hrakoto]

Hi toleda, is HDMI audio compatible with conexant cx20590 chip ?
I'm stuck with it. Everything is OK except hdmi audio.
Here is my DSDT and ioreg if you can figure it out.
HD4000 is working with DSDT(no enabler....), patched appleHDA.
my machine is a lenovo U410.

Seems like nobody figures this out yet for lenovo Ux10 laptop.

Thanks for your help.

Can't answer your question with an IOReg that does not have an HDMI device plugged. Make a new IOReg.

Two choices:
1. Set framebuffer to 0x01006601, native HDMI, port 0x5.

Hello
I have the same codec, and wanted to activate my HDMI audio.
Which of you followed? 1 or 2?

It is not a codec issue, it is a working framebuffer issue. hrakoto used 2.

Ok
Please see my IOReg and DSDT, the file is two ioreg with HDMI cable, and without HDMI cable.

I only have video, I have no audio.

EDIT: I did the second option you recommended for hrakoto.

My TV is not available now, but according to DHCPiManager, HDMI audio work?

There is no evidence of the framebuffer edit. The 02 05 connector appears in many framebuffers. Find 03 00 66 01, then edit the 02 05 following.

 

[Allan Oliveira]

the line code should be this? right?

03 00 66 01 01 02 04 02 00 00 00 04
00 00 00 01 00 00 00 20 10 07 00 00
10 07 00 00 00 00 00 00 00 00 00 00
00 00 00 00 F0 D9 00 00 00 00 00 00
01 00 00 00 02 00 00 00 30 00 00 00
02 05 00 00 00 08 00 00 06 00 00 00
