Hey Toleda,
Just wanted to share some findings, specially after I saw some people asking the same question before and had no answers.
Some folks complain about not having microphone, both from front and back ports, and I think it might be related to the SSDT.
TLDR: if after applying the ALC patches + SSDT the microphone doesn't work, perhaps the person is using the wrong SSDT, and although HDMI/DP will work perfectly, that will mute the mic.
I reapplied the entire Clover ALC892 + zml.zlib files + realtekALC.kext + SSDT and now EVERYTHING works, including the microphone that never did. The problem? The SSDT, which apparently changed between then and now, but that I had never checked in the past months.
So here is the whole story.
So, here is what I have:
- GA-Z87-D3HP with ALC892
- AMD Radeon HD 7950, and I wanted to have HDMI/DP output too
- Intel graphics disabled
- Mavericks 10.9.4
Months ago when I applied the ALC892 Clover patch and used one of your SSDTs, I had audio out, although every now and then when I plugged or unplugged the microphone it would cause a kernel panic, but HDMI/DP output worked flawlessly.
I put that to rest without the onboard audio, ended up buying a USB headset and it worked for me for a while. Every now and then I would check to see if there was a change to the ALC thread and tried to review my work, but it never gave me different results, until now.
Recently though, I found myself in need of using an old microphone and therefore needed the onboard audio to work again, and I threw myself into it.
After several reboots, I finally decided to check the SSDT and remove it, and then the microphone worked absolutely perfectly, including ambient noise cancelation (on the back port).
Then I decided to check your the HDMI page (Mavericks: HDMI Audio AppleHDA) which lead me to the CloverHDMI page (audio_CloverHDMI) which in turn lead me to HDMI 8series Git hub (audio_hdmi_8series), and in there following the instructions to choose from P0P2 or PEG0, having found P0P2 using MaciASL, I choose the audio_ssdt-hdmi-ami_hd5k-amd-nvidia-1_v2.zip SSDT, which has a definition block of "ami8hdm1".
Switching those SSDTs, from the old "ami8hdm2" to the new one "ami8hdm1" solved the muted microphone problem.
Thanks again for your great work, I hope this helps somehow.
