No Sound - Realtek ALC AppleHDA [Guide]

[zedoc]

Hi,

Thanks Toleda for the guide, i've managed to patch my audio with your

audio_cloverALC-100.command

for CLOVER under YOSEMITE

Problem is:
the sound is ok when testing the green output on motherboard but when i plug my headphone on front panel (internal speaker turn ok to headphone in sys pref) the sound is completely distorted, i hear a some weird glitches, i can hear music but the voices are almost muted with a sort of reverb effect...Also It was working with MAVERICKS.

if you have an idea...

Pinconfig is correct. IOReg shows Internal Speakers.

Maybe because i did "iojones" with headphone unplugged, here si "iojones" with head phone plugged and unplugged.

(also i had the same "headphone weird sound issue" trying multibeast 7.0.1 audio patch on a previous clean install)

I did try it as you describe, but all in vain
No Audio / GA-Z97M-D3H / ALCxxx 887

Must be something peculiar with your hardware.

IOJones does not show an audio apps.
What did you try?

Yep, same problem under Windows 8 64bit...i'll check the front panel connections tomorrow, maybe my recent bios flashing...

Truly to say, i did not all understand what to do. it was to complex for me.
It would be good to could solve it.
May you tell me in a easy way what to do ?

At the moment i did find my workaround with a USB Soundcard, but the internal Sound would be my target to solve.

First thank you for this thread, and all the help.

Cannot get internal sound to show as an option.

Problem solved by unplugging-replugging front panel to motherboard and adding a small ferit around the cable, thanks
