I don't know what motherboard you have, but here's my drivers for the DS3L with ALC888:

1. In the "Kext" folder, use Kext Helper to install the HDAEnabler driver
2. In the "Taruga" folder, drop the codec txt file onto the Turtle icon to patch the audio driver
3. Reboot
Make sure that Audio is enabled in the BIOS!
