HDMI audio problem with DTS//AC3/multi channel

[gerardpuducul]

ok !

so in fact i don't need to modify the file

because my card is already in P0P1 isn't it?

and these line will do all the modification in the dsdt

# 3. Rename device P0P1 to device PEGP
into device label P0P1 set_label begin PEGP end;
into_all all code_regex P0P1 replaceall_matched begin PEGP end;
into scope label _SB.PCI0.P0P1 set_label begin _SB.PCI0.PEGP end;
into scope label \_SB.PCI0.P0P1 set_label begin \_SB.PCI0.PEGP end;

thks

Yes.

so I continue my fight!!

Step 1 : remove voodoohda : Done
step 2 : install the native AppleHDA : Done using pacifist on 10.8.2 update and install with kextwizard
Step 3 : install moutain lion with your guide.
DSDT patched with hdmi_audio_ami_5_series_amd-nvidia_discrete_graphics untouched : no error / some warning
replace the original dsdt with the new one in my extra folder

reboot

I had of course already reboot!

I think maybe 10 time! and i have always the same error!

the only thing that make me reboot successfully is to add the option DSDT=null to chimera!

I am desesperate!!

Boot with DSDT=Null, delete Extra/dsdt.aml, restart. Attach the problem dsdt.aml.

OK My Master!

Here is my problematic dsdt (and my original working dsdt too)

Thanks

I only download zip files. Use Finder/File/Compress.. to make zip files in OS X. Remove the 7z files and replace with zip.

OK my fault i am completly stupid I had saved my modified DSDT in a wrong format! Very stupid!!

So now my hackingstosh boot but i have no sound device found!

here is the 2 DSDT files (in zip format)

thanks

I don't know where the problem is in DSDT_MOD_FOR_HDMI.aml; trash it When I apply hdmi_audio_ami_bios_hd3000.txt patch file to DSDT_OK.aml, I get a different number of lines than you get in DSDT_MOD_FOR_HDMI.aml. It looks like you changed the patch file, why?

Suggest you apply the hdmi_audio_ami_bios_hd3000.txt patch to DSDT_OK.aml (as is) and install.
