5.1 sound on ALC888S


4 posts in this topic

Recommended Posts

I'm using a modified AppleHDA.kext which makes the 2.1 sound and Mic work but I got new 5.1 speakers and I can't get them to work. There split up to 3 different outputs in the Sound preferences. I've tried joining them together as seen on some YouTube tutorials but it still only plays through far left and far right, left and right or bass and center.

I can't get them all to work at the same time. Any ideas?

i've seen this post: http://www.insanelymac.com/forum/topic/293001-mavericks-realtek-alc-applehda-audio/ but I don't understand what to do..
