No Sound - Realtek ALC AppleHDA [Guide]

[toleda]

found a way to fix it by setting input gain to 0 with the slider in voodooHDA

AppleHDA only, off topic.

Hi there,
New builder having audio driver failures. Any help/insight would be appreciated!

1. All attempts at installing audio drivers has not worked; no audio devices detected.
Verifying failure by checking audio through iTunes, System Preferences (Audio), & About This Mac>System Report> Audio. No audio devices installed.
2. OS X 10.10.5 Yosemite/ ASUS Z97-A/ BIOS VERSION: 2801 x64/ Intel i5-4590/ Intel 4600
3. MultiBeast> DSDT Free> Realtek 892, and Optional Intel 4000 HDMI

11. NZXT S340

**Audio works when booting into Windows 10.
***I've also noticed that the Chimera Bootloader hasn't worked, maybe MultiBeast driver building issue?

Best,
Nick

1. No sound
2. El Capitan 10.11.4

• Intel MOBO DG41TY

• BIOS version TYG4110H

• 2.33 GHz Quad-core Xeon

• Sapphire HD7770

I have Realtek ALC-888-VC
I've tried adding with multibeast(888 and 888Legacy) I tried others (887/888b,etc...) and they give me no audio output devices in system prefs. So it seems Multibeast is correct.
Scouring the internet for answers and trying all different approaches. but still no sound.

anybody have any ideas or help?

getting full video acceleration took me weeks to achieve, but finally got it. This is the only issue I have left.
please help

My speakers are attached to the back green audio output. I've also tried the front panel and no sound.
In system prefs/sound I get 2 audio line out ports. I try both neither work.

Missed Post #1/I. No Sound/1. Audio Outputs/1. Speakers
Both Line Outs are wrong. No sound always occurs when the audio device selected is not connected to the speakers.
