AppleHDA by tmongkol in SL 10.6.3
For those with audio chip like this (ALC889a, mother board Gigabyte EP35-DS3r, using AppleHDA.kext) who have lost sound with Snow Leopard 10.6.3 and don't like VoodooHDA.kext due to the very low volumes, here it's a possible solution.
Tmongkol has a thread in another forum, "ALC889A, Gigabyte (Intel), and other ALC88#(x)", which offers some LegacyHDA.kext that, added to vanilla AppleHDA.kext and HDEF code in DSDT, has returned the excellent sound I has before. How to: - install vanilla AppleHDA.kext from Snow Leopard 10.6.3 - install LegacyHDA.kext from Tmongkol (links in the first post, besides "Series of LegacyHDA.kext for Gigabyte ALC888 and ALC889a 10.5.8 & SL Ready"), I've tried the kext in the folder "3out2in HDA headphone" - modify DSDT: 1. Find ... Notify (\_SB.PWRB, 0x02) Notify (\_SB.PCI0.AZAL, 0x02) ... and replace ... Notify (\_SB.PWRB, 0x02) Notify (\_SB.PCI0.HDEF, 0x02) ... 2. Find "Name (_ADR, 0x001B0000)", usually it's the sound device, and change to: Code:
