Ok guys I'm running O.S. X86 and works ok. I have installed for the Audio VoodooHDA kext and the audio works fine (stereo). But obviously i want the 5.1 audio. My mobo it's an asus M3N78-VM and the chipset audio is a VIA VT1708B. So into my bios I have the option for change the azalia audio to internal or external codec. Internal is for HDMI Audio and internal for VIA or I can choose both of them.

I was tried installing ALC 883 kext but nothing ALC888 and nothing. I was wondering if I just can't choose those kext (ALC) because my audio chipset it's via, not realtek, but the audio is HDA. I've installed ALC1200 and now in the system profile-Audio built-in appers:

Intel High Definition Audio:

Device ID: 0x10438345
Audio ID: 12
Available Devices:


and that's all. Whit only VoodooHDA appears nothing. Now what I can do?
