Hello, again, Mirone. I further investigated, starting from the HDA kext who sent me and I got everything to work ok. I have done the following: 1.I reconfigured Platforms.xml and layout12.xml from AppleHDAPlatformDriver.kext of 1.7.4 version of AppleHDA.kext that had been using since Snow. 2. In info.list (configdata) of AppleHDAHardwareConfigDriver.kext, I have also used the 1.7.4 version With these changes everything works correctly. Only slight problem not solved: Every 50 seconds, exactly, the kernel delivers 4 times the error messages "Sound assertion in AppleHDAWidget at line 2122", that's all. Now I'm researching, using your guide, and I'm trying to patch AppleHDA.kext native ML, ie from version 2.3.0. I have not achieved anything. No I do wrong, or maybe the settings need to be different. I'm patching from ADI 1984B. Is that correct? or in ML must use ADI 1984 or ALC 885? Always from Layout ID 12?, as it is in DSDT? My weak point of the whole process is the Platforms.xml, then I lose. Maybe that's why no work. I can help achieve this, if possible? Thank you very much for your cooperation.

Hello Mirone. Thanks for your feedback. The file you sent me works, but only half. Consider: positive: 1. Now the sound icon in the menu bar is enabled and the volume control works. 2. In Preferences detects the device and controls work. 3. System Information shows all the components of the device correctly. 4. The internal microphone works. negative: 1. There is no sound from the internal speaker. But if you hear when you connect headphones (although the sound is poor). 2. No Preferences detects change internal to external devices. 3. No chance of noise reduction for the microphone .. 4. Multiple kernel error messages like "Sound assertion in AppleHDAWidget at line ..." Can you help to solve these problems? I've been trying for several days but nothing works. A greeting.

Hello again, Mirone. For if necessary I attach the "codec dump" my ALC268 extracted from Linux. Thank you. IFL90_-codec_0-Realtek_ALC268.txt.zip

Hello again, Mirone. I forgot. I also attached my patched AppleHDA.kext. Thank you. AppleHDA.kext.zip

Hello Mirone, I followed your tutorial step by step: http://Olarila.com/forum/viewtopic.php?f=3&t=2168 but I have not gotten anything. In info system detects the audio info, but no preferences any audio device. Can you help me ? My audio device is the signature and I attached my DSDT patched. Thanks. DSDT.aml.zip
