kosakgroove Posted February 19, 2016 Share Posted February 19, 2016 Hi guys! I got sound working in the first laptop in signature thanks to Mirone and his patched AppleHDA for ALC233. Then a nifty user helped me enable the internal microphone in my AppleHDA, because not even Mirone managed to after two tries. Now it works, but it is at a very low volume. This is when I whistle, and it is the loudest noise that the mic picks up: As you can see ambient noise reduction is disabled, so it is a very poor quality sound, but that still seems like a person shouting from 3 km away. If I enable it, there is no sound at all being recorded by the internal microphone. This screenshot below is of when I shout, with my face close to the webcam (where the mic is) with ambient noise reduction DISABLED, notice how low the volume it picks up That is precisely why Dictation features of OSX dont work.... It tries to pick up my voice, but it never is loud enough for it to detect. That feature would be great for my job.... Being able to just say to the computer what to write. Would save me hours of looking at the screen. Also I would be able to skype anytime, and as I use Mac OSX as my daily driver, for entertainment and work, Skype is also an important part of my job... If you would help me fix this and boost the microphone volume,I could talk to my GF and my bosses without having to boot windows just for that.. My USB microphone is the one from Guitar Hero II (very poor quality, even the internal one performs better, at least in Windows) I am therefore attaching all my ACPI files and my AppleHDA, so maybe YOU could help me figure out a way to fix this issue... AppleHDA.kext.zip kosakgroove ACPI.zip Any suggestion is deeply welcome and appreciated. BTW I use layout-id 3 in the DSDT and MacbookPro 11,2 SMBIOS. HDMI audio, headphone/microphone jack and speakers work perfectly, boosting the volume of the internal microphone is the last concern, and the biggest one I had since the beggining. How ironic. Thanks in advance. Link to comment Share on other sites More sharing options...
kosakgroove Posted February 21, 2016 Author Share Posted February 21, 2016 Here go all the files and codec dumps that Mirone requests for patching. Something that i have noticed in the meantime is that most of the times the microphone simply stops working after sleep, even with me having CodecCommander and knowing that the rest of EAPD devices work well, before or after sleep. I would reallly apreciate some feedback on this. Mirone.zip Link to comment Share on other sites More sharing options...
kosakgroove Posted February 23, 2016 Author Share Posted February 23, 2016 I would love a bit of help, please,I cant figure how this works to boost the microphone. If it cant be done just tell me and maybe you could give me some guidance on replacing the webcam and microphone of the laptop with an iSight or Facetime HD camera ????

En0r1m Posted February 24, 2016 Share Posted February 24, 2016 I do not understand anything AppleHDA, since I found this kext of Mirone somewhere on the Internet I am sending you so that you can test. It is a version 10.11.3 AppleHDA-272.51.3-ALC233.zip Link to comment Share on other sites More sharing options...
kosakgroove Posted February 24, 2016 Author Share Posted February 24, 2016 Well, microphone is working with that one, but it has the same problems than my custom patched AppleHDA. Does anybody know of any way to boost the microphone input level? If no, how should one proceed in order to exchange the integrated laptop webcam and microphone (which suck ) with a Facetime HD camera or a iSight?
