Asus X79 Rampage IV Extreme (ALC 898) with OSX 10.10.3

Suddenly, no sound come out from the speaker. It was OK before. Tests were made many times but in vain. A clean install test was even made with Multibeast 7.3, no DSDT installation but still no sound. Please see the attached files for details. It is strange for me.


Many thanks for your help!

Device detected, but no sound even when set to 100% volume. Tried all ports on the motherboard, even headphones.
Specs: MSI Gaming 7 x99, i7-5820k, R9 280X. Latest Yosemite fresh install.

Installed using cloverALC. I have attached the files. Thank you.

Hi Toleda
please have a look at this for me; Yosemite not giving me any audio joy on X79 UP4

thanks in advance - your efforts are greatly appreciated

1. No Audio from any Rear ports even though codec is loaded
(Previous 10.8 & 10.9 installs on same hardware audio working perfectly)
currently using temporary solution USB C-Media Adapter - working sound but USB solution problematic/cumbersome for my workload/setup
several clean installs attempted for each fix over many days

2. OS X 10.10.2 and 10.10.3 / GA-X79-UP4 (rev1.0) / BIOS F7 / i7-3930K / ASUS GTX 770

3. No Sound - Realtek ALC AppleHDA v1.1 by Toleda
audio_realtekALC-100_v1.0.4b.command - install success, no sound
Piker Alpha method AppleHDA8Series - install success, no sound
Multibeast 7.2, 6.1 - no sound
Jimi Hendrix at max settings whilst heating motherboard in microwave oven (also max settings) - no sound
3.1 screenshots attached

10. clover not installed
11. 1- various Bose Headphones, external amp, Apple iPod headphones
