Hi all,
I've modify some value of AppleHDA.kext that support speakers, headphone and ext-mic-in of Lenovo Y410.

My Lenovo Y410 using Realtek ALC262 with sub-id: 837 (another sub-id could not work with this kext).

For whom are using Leopart 10.5.x. This is working for you.

To install use Kext Helper install ALCinject.kext and AppleHDA.kext.

Thank you for interest my thread.
