Microphone Through TRRS Jack Not Detected in Windows

Manually adding other drivers section doesn't work. The driver has been digital signed, any bits you modified in the driver kit, it will break the checksum algorithm, and the driver installation will be failed (due to checksum failure). There is no other ways to bypass this except pushing Apple/CirrusLogic to update/sign the driver.

You can always disable Driver Signature enforcement in W10. 😉

Is there a way to uninstall the current audio driver on my Macbook Pro Retina Mid-2012 Windows 10 partition and forcibly install the Cirrus Logic 4208 (AB 93) driver? I tried downloading the 4208 AB 93 driver from Cirrus directly, but when I install it, it doesnt do anything. I disabled Driver Signature enforcement and tried it, it still didn't do it.

I see you are very knowledgeable, as I see your responses almost everywhere in the BootCamp section. I really want my Apple Headphone mic to work on Windows 10

Is your MBP a 13-in or a 15-in? On a 13-in, the drivers are as follows.

You can uninstall the driver, delete the devices from the Device Manager and reboot and check what unknown devices show up after the reboot.

After I uninstalled all of my audio devices and restarted They just reappear as "High Definition Audio Device" how can I get Cirrus Logic 4208 (AB 93) installed? FYI No audio works, the signal meter on the playback tab does move when playing something, but no sound and I also now have a red light coming from the headphone jack (headphones actually work for system sounds when plugged in though, but app sounds still dont go though)

Is there a reason, that you want the specific 4208 (AB93) installed? I suggest you install the drivers from the BC Drivers package valid for your specific Mac model.

From what I've read on various forums is that, that particular driver supports the microphone on the apple headphones, i.e. supports the TRRS port for microphone. For some reason, in the original poster's case, on a 2013 Retina mac it supports it, but the 2012 retina doesn't get the same driver thus no mic support (even though the hardware is virtually the same)

I keep trying to download Windows Support Software through the Boot Camp assistant, but its deathly slow and every so often it stops downloading and says there was a Network Problem then I have to restart the download 😟

1. Try a wired connection, if possible.

2. The issue is not the specific driver, but Windows itself. Previous versions of Windows do no correctly handle the notifications from the driver for the microphone part.

3. The default driver for your specific hardware will also work.

4. If BCA does not work to download the driver package, you can try https://github.com/timsutton/brigadier and download it manually. Here is a log. Please see Apple Software Update not finding Bootcamp 6.0 driver package as an example.

I appreciate your help. I actually found Boot Camp Support Software was saved on my Bootcamp partition and repaired all the installs... I now have Cirrus Logic CS4206B (AB 40) installed. It does not recognize the mic from the Apple headphones. Should I try to uninstall the driver or delete the device and start from there? I just want it to support the mic. When I uninstalled the driver the mic did show up for like 10 seconds previously then disappeared for some reason leaving the internal mic the only option, then all of my audio playback and recording device drivers reverted to "High Definition Audio Device"

I have played around with the Device Manager and it appears that when I disable the driver "Cirrus Logic CS4206B (AB 40)" under "Sound, video and game controllers" it also disables all of my sound devices.

Can you check the PlayBack and Recording settings under Device Manager for the list of devices that show up?

Using a BT version of TRRS (almost) with a Motorola S9, I get. The Driver supports it correctly, it is Windows which fails to acknowledge TRRS.

Can you check if there is a faint red light in your Audio jack? Do your headphones work even though the microphone does not?

When I have my Apple headphones with mic plugged in this is what playback displays. Only the internal mic appears under the recording tab. BTW I updated my previous response with an image of my devices. Yes the headphones do work, the mic doesnt show up though, the red light is no longer there since I repaired the boot camp drivers.

***Just to try it out I uninstalled the Cirrus Logic CS4206B driver under sound and controllers and my sound stopped working. I restarted the computer and it automatically reinstalled the same driver.

Okay, so I uninstalled it again, but this time had it delete the driver info. After I restarted it didnt reinstall the driver and said "high definition device" again. No microphones were detected (including the internal one.) I went to the Cirrus Logic driver folder in the boot camp folder and tried running the CS4208B.exe and it didnt do anything, but when I ran the CS4206B it reinstalled the AB 40 varient of it again. It seems the driver .exe files check for which macbook you have and installs the driver Apple deems appropriate for your computer.... so I dont know how to forcibly install a different one.

The driver is determined based on Vendor ID and Product ID exposed by the underlying firmware/hardware. You cannot change it under normal circumstances.

You have the correct driver. Under W10, it should recognize TRRS. If it does not, try to insert slowly in the audio jack, which may generate separate interrupts.

Microphones do not show up in Playback devices, they are Recording devices.

Yeah thats what I said previously, that the mic doesnt show up under recording devices. So it sounds like there isnt anything I can do if I want the Apple Headphone Mic specifically to be recognized

See the post by hanshan44 in this thread. In that case, it is working.

Yeah, he just has a different driver from me so the mic on the Apple headphones isnt supported with my driver 😟 Maybe other TRRS headsets do work because they run with their own drivers, but my friend with an Alienware computer supports the Apple headphones. Maybe I can ask him to see what 3rd party driver supports the apple headphones mic. I guess I'll first test other TRRS headsets and see if they are supported before I go that route. Thanks
