Hi,
have you injected HDEF+ALC892 in DSDT?
If no, post your DSDT

High Definition Audio, the patch is included in DSDT Editor; if you are not able to apply patch post DSDT.
Tomorrow i apply the patch and repost file.

Hi,
If the kext not working properly try this; the archive contains DSDT with ALC892 and zero warnings + Kext AppleHDA

Download and install the kext posted by Arthur, if doesn't work download and install my archive; put DSDT in /Extra (rename it DSDT.aml) and install AppleHDA.kext (use Kext Wizard).
Reboot and enjoy
