Hi Toleda. I was wondering if you could help me, I have read your guide. I just hope i've answered the questions correctly. Sorry if I have missed anything obvious.


  1. “No Output Devices Found” in system preferences
  2. OS X Yosemite 10.10/Gigabyte G41M-Combo Revision 2.0/BIOS version: FA, BIOS Date: 02/29/2012/Intel Core 2 Quad Q8200/nVidia Ge Force GTX 260 896mB
  3. I followed this guide. I believe I have an ALC887. I patched my DSDT with audio ID 1 using MaciASL no errors. Used multibeast and selected realtek alc887 legacy. Audio ID appears to be listed correctly as does Audio codec. Still no sound though :(
  4. Attached. File name is ioreg.ioreg
  5. Attached.
  6. N/A
  7. Sorry, I don’t understand this step. I hope i did it right. File name is kernel sound assertions.
  8. Screen shots:
    1. Attached. File name is DCPI tools screenshot
    2. Attached. File name is System Info screenshot
  9. Chimera/Chameleon (if installed)
    1. Attached.
    2. Attached. File name is DCPI boot log
    3. Attached.
    4. N/A

Thanks toleda!

Removing that dict didn't work. Will test with a new TonyMacx86 standard config.plist later on.
