INSTALL WINDOWS 10 DRIVERS FOR MACBOOK PRO WITH BOOTCAMP Open Boot Camp Assistant, and click on 'Action' in the menu bar.
No sound after upgrading to Windows 10? It’s probably a driver problem. Your audio driver is probably missing or out of date (and therefore incompatible with Windows 10). So it’s usually a pretty quick fix.
Most of the time, you just need to update your audio driver. Here’s how STEP 1 – Confirm it’s a driver problem To confirm if your PC sound problem is caused by driver issue, you need to check for the driver status in Device Manager: 1) On your keyboard, press the Windows logo key and R at the same time to invoke a Run command.
2) Type devmgmt.msc and click OK. This will start the Windows 10 Device Manager. 3) In Device Manager, expand Sound, video and game controllers. Under this category, you’ll see Realtek High Definition Audio. If there’s a yellow mark next to the device name (usually an exclamation or a question mark), there’s problem with the driver, and you need to update it. E.g.: STEP 2 – Update your audio drivers There are two ways you can update your audio drivers: – You’ll need some computer skills and patience to update your drivers this way, because you need to find exactly the right the driver online, download it and install it step by step. OR – This is the quickest and easiest option. It’s all done with just a couple of mouse clicks – easy even if you’re a computer newbie.
Option 1 – Download and install the driver manually You can download Realtek audio drivers from Realtek. To get them, you need to go to the website, find the drivers corresponding with the sound card model and your specific flavor of Windows 10 (32 or 64 bit) and download the driver manually. Once you’ve downloaded the correct drivers for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver. Option 2 – Automatically update Realtek audio drivers If you don’t have the time, patience or computer skills to update the Realtek driver manually, you can do it automatically with Driver Easy.
Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee): 1) and install Driver Easy. 2) Run Driver Easy and click Scan Now button.

Driver Easy will then scan your computer and detect any problem drivers. 3) Click the Update button next to the Realtek driver to automatically download and install the correct version of this driver (you can do this with the FREE version). Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

Modified Driver for Windows XP. 1.0.0.13b (Oct. 27, 2009).
1.0.0.13c (Nov. Try this if recording still fails with 1.0.0.13b, but it probably won't help. Cirrus Logic has a newer (Jan., 2011) that is reported to fix audio output problems, but still not record properly. Windows Vista and newer: Cirrus has a new driver that should work. Unfortunately, their link is dead, so here's a copy: This driver also works in 32-bit versions of Windows Vista and Windows 7, however there is a newer driver set where the Vista driver seems to be fixed.
Windows XP driver 1.0.0.32 is not fixed, while 1.0.0.38 appears to fix audio playback but not recording. New drivers are available from. There are two variants of the driver included:.

Cirrus Logic High Definition Audio MacBook. Cirrus Logic High Definition Audio MacBook, No S/PDIF Out Both versions enable the midrange speaker and corrects the volume. The 'No S/PDIF' version also turns off the S/PDIF optical output. Installation of the modified driver follows standard procedure: In Device Manager, Update Driver for the Cirrus Logic High Definition Audio device. Don't let Windows search for or do anything automatically. Manually choose to the driver from a list, and use the 'Have Disk.'
Summary of Changes This driver is a modification of clhdaud.sys version 1.0.0.13:. Enables the third (midrange) speaker in the MacBook Pro.
Removes the -16dB volume limit on the speakers, and applies it to the headphone output instead. The 'No S/PDIF' variant turns off S/PDIF optical output. 8). Fixes recording issues for most sample rates in Windows XP (except 96 kHz). (New in 1.0.0.13b, Oct. 27, 2009).
The recording problem isn't completely fixed in neither version b nor c. If 1.0.0.13b (96 kHz) doesn't work, try 48 kHz instead.
(1.0.0.13c only, Nov. 1, 2009) Description As per a thread on Apple Discussions , Apple/Cirrus Logic appears to have shipped incorrectly-configured drivers for the MacBook Pro's audio device in Windows XP. Windows Vista uses a different driver and has its own independent set of problems. In the Windows XP driver, there are two causes of low audio volume:.
The MacBook Pro has three speakers. The midrange speaker was not enabled. The speaker amplifier gain is scaled by -16 dB in software, while the headphone amplifier gain isn't.
The modifications to the 1.0.0.13 driver addresses these two issues. 8, 2009) The driver also attempts to correct recording issues (1.0.0.13b, Oct. When recording, depending on the sample rate used, the driver has been observed to up-sample the received audio, returning 2x or 4x as much data as an application expects, leading to distorted audio. Version 1.0.0.13b corrects two instances of buffer overruns in the driver, resulting in most sample rates working correctly. In the IMiniportWaveCyclic::NewStream handler, the driver rejects requests for new streams for sample rates it does not like. Oddly enough, sample rates that NewStream declares legal will record incorrectly. Version 1.0.0.13b accepts only 96 kHz as a valid sample rate, but this seems to fail in Vista.
1.0.0.13c accepts only 48 kHz instead, which I hope will at least partially work in Vista. Due to popular demand, the 'No S/PDIF' variant also turns off the digital optical output (red light in the MacBook's headphone port). It will remain disabled even if an optical cable were plugged into the headphone port: The jack detection routine does not control the optical output. The optical input should still be enabled, but I haven't tested it. This modification of the driver has been tested on the following machines:. MacBook Pro MC118LL/A (15') Use at your own risk. Without the driver's source code, I could not ensure that the modifications did not introduce subtle side effects.
Previous Versions. (Aug. 8, 2009) Hardware Details Some observations that may be useful for writing drivers for the CS4206A on a MacBook Pro:. The XP driver sets two of the four GPIO pins to output '1' (0xa for direction717, data715, and enable716).
Pin3 turns on and off the midrange speaker. I haven't observed any effects from toggling pin1. There are DACs(?) at Node ID 2, 3, 4, and 8. These drive the headphone port, internal midrange speaker (right channel only), two internal stereo high-frequency speakers, and digital output, respectively. The XP driver sets the channel/stream ID706 and stream format2xx for all of these nodes when playing audio.
(Unmodified original driver did not set them for NID 3). The ADC for the microphone has Node ID 6. 5 seems to be for the Line input, while 7 appears to be the digital input. Enabling/disabling S/PDIF output is done using verb 70D (set digital converter control) on NID 8 The Intel High Definition Audio specification can be found.
