No Sound - Realtek ALC AppleHDA [Guide]

definitely getting *some* sort of output now

Likely an issue specific to your system.

Hmm, I shall continue to investigate, maybe something related to the "built-in rear audio amplifier" advertised on the back of the box that CodecCommander isn't handling. Edit: Or the fact that this board has an optical out instead of a 6th 1/8" like a lot of boards seem to -- perhaps I need to alter the layout.xml in some fashion.

I'm a fairly technical sort, but any suggestions on where I might start looking? You know the audio subsystem so well, any pointers might be appreciated. Thanks again!

Edit: Looks like I was mistaken, CodecCommander didn't actually do anything. I just hadn't cranked volume to absolute max in both system and iTunes before, which was necessary to hear the occasional static and high-frequency bursts. Verified it's loaded via kextstat just in case

Edit the second: It appears the culprit is Windows 8.1. If I power down and unplug main power, wait 30 seconds, and boot into Yosemite, green port works as per normal. If I boot into Windows, even to the login screen, green port ceases to work until I cold start again. Odd...apparently not an actual no sound issue, apologies for the clutter!

Used 2 Audio ID injection methods and an old AppleHDA.kext. Two enablers disable audio. Suggest MultiBeast 7/Drivers/Audio.

Thanks, now the things not working are the hdmi audio and input. These are the only files on the Mac

You have all the files noted in Post #1, Problem Reporting. IOReg shows input working. HDMI audio is off topic, see Audio - HDMI Audio AppleHDA

No it does not, the original was with the mavericks 6.1 driver plus the 7. Are you sure that you have red the new ioreg?
