MacBook Pro Audio Driver

Which audio driver is used by MacBook Pro 7.1??? I'm running BootCamp (Windows7 Ultimate x64) and I'm having a problem with audio input, so I'm looking for anything taht will make it work.

In Device Manager I had "Cirrus CS4206A (AB13)" and three devices of "NVIDIA High Definition Audio". Then somehow I updated Cirrus driver to "High Definition Audio", but Audio-IN is not working, only Audio-OUT (The same thing with Cirrus). Just to mention, my MB is using only one "multi" audio jack.

The thing I can't understand is - Is MacBook Using Realtek Audio, stupid Cirrus or NVIDIA Audio ???


I can't contact Cirrus Support, because on their website it's written:

We produce integrated circuits that manufacturers design into their audio and video products. We do not manufacture graphics cards, sound cards or modems.

Your retail manufacturer is responsible for your product support. Please contact your manufacturer or visit your manufacturer's Web site for driver support.

These generic drivers may have been modified by the electronics manufacturer to suit a particular product. We recommend that you contact your product's manufacturer for support.

I contacted Apple Support (Chat) and the person I got on the chat is a noob! He told me to uninstall BootCamp or whole Win7...And he gave me a link to Microsoft Support... So, nothing really helpful, he just bumped me to Microsoft...

When I install Realtek HD Audio Driver/Codec there are no changes and no Audio Manager running!!


I mean who else is using stupid Cirrus -Citrus- s**t...I tought I bought good laptop for my job, but this is not usable for me in this situation...


Anyone can help?

MacBook Pro, OS X Yosemite (10.10.1), 13inch ; Core2Duo ; 4GB RAM ; NVIDIA 320M

When I remove Cirrus and NVIDIA High Definition Audio drivers, they are getting replaced with "High Definition Audio Device"...


None of the devices in the "Sounds" window are working...They are showing like working fine, but no output on integrated speakers and no output from 3.5mm jack and no input from internal mic/in jack

As I said integrated microphone is not working and jack is not functional...Also there's red diode turned on in the jack hole

#EDIT

Then I uninstalled Windows's default audio drivers "High Definition Audio Device" to get sound device without drivers and I quickly made a screenshot before they are installed again... And as you can see they are recognised as "Audio Device on High Definition Audio Bus"

What can I do now? :/

Mar 23, 2015 6:56 PM in response to Loner T

Oh bro I tried re-installing those drivers many times, but no luck! 😟 I contacted Apple's ChatSupport and they told me that this is not their problem, because it's related to Microsoft (Windows)...So now I finished conversation with Microsoft Expert over chat and they told me that my audio driver is outdated and not fully compatible with Windows 7. So, stupid Cirrus (which I've never heard of before) is not updating their drivers. Microsoft expert suggested me to contact CirrusLogic Support, but there is no mail and I'm not in USA - so dialing their phone number is too expensive...


I really don't know what to do. This is Apple's false, because they don't really care if customers are satisfied. They are not forcing their suppliers to update drivers. Anyways, which model is your MacBook (which year) ?? Do you suggest trying Win 8.1 or XP ??


Thanks for being active on my topic! 😉

1. Your MBP 7,1 seems to be a 13-inch Mid 2010 MBP with nVidia GT 320m.

2. What is the Cirrus driver version currently installed on your MBP?

3. As a test,

a. Create a System Restore Point.

b. Remove both nVidia and Cirrus drivers.

c. Reboot Windows.

d. Check which unknown devices you get in Device Manager and post a screen shot from Device Manager.

The "red" diode is the Optical laser. There is a microswitch which controls if your combined analog/digital port will output digital signals or analog signals. If you insert the headphone in the port and take it out (you may have to repeat this till the laser turns off), then you can install the BC drivers and test.

Mar 24, 2015 4:55 PM in response to Loner T

Yeah, output working fine (switching correctly between earphones and integrated speakers)...For input i tried Apple Earbuds, some PC headphones with mic (tried connecting with splitter) , my Guitar and Sony mic .


Today I downloaded the lastest driver from Cirrus website but no luck -

CS4207 Windows 7 (32/64-bit) and Windows 8 (32/64-bit) Driver
3/2013, v6.6001.1.39 : 107 KB


I would like to contact CirrusSupport, but I don't know how...
