# 5:1 Channel Audio not working. Still I can get stereo audio through the green (headphone) port at the back of the MoBo.


So far, that's all. I didn't even have to enter any boot flag to get the installation window. Didn't have to use any custom KEXT or anything.

5:1 / 7:1 audio you have to set up through the midi app.

I tried but it didn't work for me. I followed this guide: http://www.tonymacx86.com/130-how-enable-5-1-channel-analogue-audio-os-x.html

Can anyone help about figuring out what may be wrong with my instance?
