What version of OS X? dsdt edits for HDMI audio are required. HD3000 HDMI audio uses a special Audio ID, 389 in Lion or 3 in ML.

2 choices for AppleHDA.kext:
1. Edit current AppleHDA.kext to remove an output audio device in the current path map.
2. Edit dsdt/HDEF/layout-id to 3 or 389, edit new AppleHDA.kext for 2 wire SPDIF.

More information on AppleHDA.kext edits, see Customizing the Optimized Lion AppleHDA.kext. For HDMI audio edits, see Mountain Lion HDMI Audio - Award DSDT.

The HDMI audio edits do not fix errors. If "do nothing" means the system does not boot with the edited dsdt, remove the edited dsdt and install the native dsdt. Verify the system boots with the native dsdt. Attach the native dsdt and the edited dsdt and a copy of IOReg. [Guide] How to Make a Copy of IOReg.

hi toleda so nothing i mean it boots but dont change the layout-id check in ioreg and is 1 and in dsdt is 3
ihave the dsdt only with the ami hdmi sound patch

You missed a very important step:
Mountain Lion HDMI audio - Verify S/L/E and org.chameleon.Boot.plist
1. Delete any and all audio enablers (HDAEnabler8??), helpers (ALC8??), etc.; AppleHDA.kext only.
S/L/E/HDAEnabler1.kext is installed. Delete the kext and repair permissions and cache. Reply with new IOReg.
