No Audio Devices - Realtek ALC AppleHDA [Guide]

[toleda]

ran IOReg

Same.
Install realtekALC.kext to Library/Extensions or use MultiBeast 9.

 

[toleda]

not working again

IOReg says audio is working.
Why is HDAEnabler2.kext installed?

 

[toleda]

No Audio Device

Something is really messed up. HDEF found the AMD HDMI audio codec instead of the onboard codec.
Attach dsdt (if edited) and/or installed ssdts

IOReg says audio is working.

My speakers say otherwise lol

I don't know why HDAEnabler2.kext is installed. As i said I hadn't made any changes at all before this stopped working. Just out of the blue it stopped after working over 10 days. Maybe I did it today trying different stuff on my own. (I don't know wtf I'm doing really so anything is possible) Anyway I've deleted HDAEnabler2, rebooted, still no luck. Although now I don't get static, just no sound at all.

No Audio Output

See Post #1 for fix:
Unsupported/Non working Realtek ALC AppleHDA

1. 100 Series/Intel High Definition Audio

My speakers say otherwise

No suggestions.

 

[TheCipher]

No suggestions.

I did a time machine backup 2 days ago when it was working, anything I could maybe restore from then that might help??? This is crazy. I don't know how it just stopped like this, so weird.

Reply with new files.

Thanks, Toleda. Edit was made, changed from true to false. Did not run cloverALC script again. All other new files attached.

Changing that parameter to false definitely removed any detection of the machine seeing the ALC888 in there. Audio codec name now not showing in DCPI Manager. No audio codec detected by detect command script.
