I apologize to everyone if I'm not very present, and maybe answer a delay. I'm working on a new project that is taking up all my free time, but you can continue to write and test.

Some people reported that external microphone works on HP laptops, if you're using a stereo microphone. I don't have one to test out.

My external microphone is visible but still does not work. I tried with LineIn and modified the corresponding verb to do this. Unfortunately with LineIn, the internal microphone starts working after 30/40 seconds after the system has booted, if I remove the LineIn, everything is perfect.

I would like to share some information about the internal mic.

 

My original verbs:

ATAPI Unknown Mic at Int Top 17 0x11 0xd5a30130 01171c30 01171d01 01171ea3 01171fd5

 

Fixed verbs:

ATAPI Unknown Mic at Int Top 17 0x11 0xd5a30130 01171c30 01171d00 01171ea3 01171fd0

 

how it looks in ML:

verbit does a great job, but it's not perfect.

 

We need to replace 01171fd0 with 01171f90 to declare mic as internal device. After all, it is internal.

....

Thx, for the tip.

 

Codec: IDT 92HD81B1X5 DevID: 287143429 (0x111d7605)

The Verb for my internal Mic:

01171c40 01171d00 01171ea3 01171fd0

I fixed to:

01171c40 01171d00 01171ea0 01171f90

 

I did as you suggested, and i got the "noise cancelation" option and the Mic is listed as Build-in, but i didn't get the volume control for it, do you have any other suggestion to try out, or any idea what it might be wrong?

Yes, the mic on skype work fine. My codec is:

 

Codec: IDT 92HD91BXX Address: 0 DevID: 287143648 (0x111d76e0)

 

Can you check if this feature is working on your Hackintosh?

Yes it work fine with my

Codec: IDT 92HD91BXX 287143648, 0x111d76e0.

 

EDIT

 

Never used it before, but you have to keep the key pressed, talking and then release, you're doing this?

Thanks, but doesn't work for me. Here is my AppleHDA, please if you have time check it. Thanks

 

Every things are working fine even the HDMI audio (patching AppleIntelFramebufferCapri). Except the "Speakable items"

Hi Micky, now am trying to patch ALC262 codec on a Sony VAIO laptop. i haven't found support on patch-hda.1.1 for this codec. I read somewhere that this codec doesn't need to be patched. Is that true?

Gracias

IDT 92HD81B1X5 working!! :star_sunglasses::guitar:

(Device ID 7605, Vendor ID 111D)

 

I just achieved native sound using this method. Output achieved on both earphones jack and speakers. Internal Mic ( inbuilt in laptop) also working, yet to verify external mic working via jack (don't have a mic :wink2: )

 

Just some assertions in the kernel log, must be related to sound output on HDMI I guess.

 

Great guide btw!! Thanks a ton!! :thumbsup_anim:
