AppleALC — dynamic AppleHDA patching

[polyzargone]

Hello @Fortitude

 

Thanks for your reply.

 

I have no working key in macOS to mute/unmute mic but I just made new linux dumps with Mute key ON and OFF. You'll find them in attachment.

 

Only difference I see in those is there (data=0/1):

 

Mute OFF

GPIO: io=3, o=0, i=0, unsolicited=1, wake=0
  IO[0]: enable=1, dir=1, wake=0, sticky=0, data=0, unsol=0

Mute ON

 

GPIO: io=3, o=0, i=0, unsolicited=1, wake=0
  IO[0]: enable=1, dir=1, wake=0, sticky=0, data=1, unsol=0

Also, I tried to use a headphone as a mic and it works even if the sound quality is awful. Here's some screenshots:

 

Auto switch from speakers to headphones

Internal Speakers which works with layout-id 33/66/71

Jack as a mic which works

Internal mic which doesn't work

@polyzargone I had a feeling that the external mic and speakers/headphones would work. Don't want to steer you in the wrong direction, but my guess is that the internal microphone is wired correctly for all of the layout-ids except 61 and 88. You'll likely need to figure out a verb command to enable it, or make sure the mute/unmute keyboard shortcut is done correctly.

 

You'll need to download AppleALC, and place alc-verb in /usr/local/bin in order to send verb commands to the codec.

You might need to run this command afterwards:

sudo xattr -d com.apple.quarantine /usr/local/bin/alc-verb

Follow this guide, and/or see if two of these verb commands will allow you to switch from the internal/external mic.

alc-verb 0x21 SET_EAPD_BTLENABLE 0x0
alc-verb 0x21 SET_EAPD_BTLENABLE 0x2
alc-verb 0x17 SET_PIN_WIDGET_CONTROL 0x40
alc-verb 0x19 SET_PIN_WIDGET_CONTROL 0x24
alc-verb 0x1d SET_PIN_WIDGET_CONTROL 0x20
alc-verb 0x1e SET_PIN_WIDGET_CONTROL 0x40
alc-verb 0x21 SET_PIN_WIDGET_CONTROL 0xc0
alc-verb 0x12 SET_PIN_WIDGET_CONTROL 0x0
alc-verb 0x13 SET_PIN_WIDGET_CONTROL 0x0
alc-verb 0x14 SET_PIN_WIDGET_CONTROL 0x0
alc-verb 0x16 SET_PIN_WIDGET_CONTROL 0x0
alc-verb 0x18 SET_PIN_WIDGET_CONTROL 0x0
alc-verb 0x1a SET_PIN_WIDGET_CONTROL 0x0
alc-verb 0x1b SET_PIN_WIDGET_CONTROL 0x0

I also see that the latest commit for layout-id 66 fixes a speaker mute disabled issue. It corresponds to this ALCPlugFix script with some additional verb commands that you can try.

 

Finally, here's a graphical representation of your codec. I'm hoping that the internal mic is your Line Out because I doubt it's a modem or another speaker.

Hallo @polyzargone

 

I have experimented with these devices many times. These new dual array microphones do not work with macOS and AppleALC.
On this laptop, use either headphones on LineIn, BT Apple AirPods or Logitech USB webcam with mic! Internal mics are not compatible.

Hello @MacPeet

 

Thanks for the feedback because I was getting nowhere with what @Fortitude proposed (don't mistake me, I'm very grateful for the help though).

I just need to replace my Intel AX210 WIFI combo card with a Broadcom one so I can use my AirPods as a workaround

Anyway, thanks both for the help!

Good morning team,

Could someone create an Apple ALC ID layout for this codec where the internal microphone works?

Thank you in advance. (Google Translate)

@PG7, ALC256 - this is a codec that is standardly supported by https://github.com/acidanthera/AppleALC/releases/tag/1.9.6.

No additional steps are required (except for macOS Tahoe)

 

The audio works on the All In One speakers, but the internal microphone does NOT work on any of them!

My request is specifically to repair the INTERNAL MICROPHONE.

Thank you for your reply.

@PG7, apparently, other layout IDs need to be tested for this codec.

Regarding those that aren't marked, the audio works but the internal microphone doesn't.

I've already tested them all!

Hello.

Have you checked to see if your built-in microphone is an Intel Smart Sound Technology device?

 

Built-in microphones using Intel Smart Sound Technology are not supported on macOS and cannot be used because they don't work with AppleALC.kext.

Hello,

unfortunately that's exactly the case.

Thank you for clarifying.

Hi everyone,

 

quick question regarding codec mapping and layout on X299:

 

On my ASUS X299 Sage 10G (S1220A 7.1), the codec is reported as 0x10EC1168 when using AppleALC and currently works with layout-id 2. SPDIF and basic stereo output are working fine.

 

However, I have not yet verified the full 7.1 channel mapping, so I am not sure whether all rear/side/center/sub outputs are correctly assigned with this layout.

 

Given that AppleALC provides board-specific layouts for some ASUS boards (e.g. ALCS1200A / ALCS1220A entries), I was wondering whether the current S1220A → ALC1168 mapping is considered sufficient for X299, or if a dedicated S1220A/X299 Sage 10G layout is available or might be worth considering.

 

This is not a bug report, as basic audio is working fine — just asking for completeness and consistency.

 

Thanks,
KGP
