mac声卡驱动，cirrus logic解决windows xp,windows7的mac各种型号的声卡驱动和麦克风问题。

含clhdaud.inf，clhdaud.sys，clhdaud_nospdif.sys等文件，很牛B，各种mac pro的windows都能用。已测试！ This modified Windows XP driver is for the MacBook Pro's (MC118LL/A) Cirrus Logic CS4206 audio device, addressing the output volume issues as described in http://discussions.apple.com/thread.jspa?threadID=2037093 -- 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 disables S/PDIF optical output. -- Installation -- There are two variants of the driver: * 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 disables 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, then manually choose to install the driver. This driver is not signed, as it is a modification of a signed driver. Fixes for Macbook Pro MC118LL/A by Henry Wong http://www.stuffedcow.net/macbook_audio
