How Can I use All channels of ALC889a to have 5.1 surround?
I am using L8v4 kexts for onboard audio realtek ALC 889a.
MainBoard EP45-DS3R. I can only get 2 channels out put. I tried aggregate device option but I couldnt get any sound. When I set aggregate device , I saw that volume control is disabled. and When I look at system preferences > sound. It says there is no output device. How Can I solve this problem? |

My sound board, ALC850, can be set to 5.1 surround through Midi Audio Configuration.
Once you've opened it select the sound output and it should give you the option to change it to 4 or 6 channels. |

you have AC97 chipset, i think it is not ALC889 chipset.
because of this you can see the AC97 6.can. can you upload, aggregate audio setting screenshots and the kext file that you use. thanks for help, eMatoS. |
