1. Description of audio problem

I see onboard audio devices, but headphones front connector sound is cracking, going on/off and sounds weird.

Green port on the back works fine.

No HDMI / DP sound at the moment (opened a different thread in relevant topic)



2. Specs:

OS Version 10.12.6

Mobo Z270x-UD5

I7-770k

Nvidia GTX 970



3. Method

Installed using multibeast - codec for 1120 + 100 / 200 series audio - got audio devices (mobo only)

Used audio_cloverHDMI-120_v1.0d.command - still no HDMI / DP audio

Tried quick fix method 1 - FakePCIID.kext + FakePCIID_Intel_HDMI_Audio.kext



4. File: audio_codecdetect.command_v2.2


HDMI audio codec(s)

Nvidia: 0x10de0071


Onboard audio codec

Device: Not supported

Realtek: 0x10ec1220

Name: Realtek ALC

Audio ID: Not supported

Current Audio ID: 1 (valid: 1, 2, or 3)

FIX, try:

1. https://github.com/toleda/audio_ALCInjection/tree/master/ssdt_hdef/

ssdt_hdef-1-with_ioreg/hdef.zip (or -2 or -3, select View Raw)

2. CLOVER/config.plist/Devices/Audio/Inject/1 (or 2 or 3)


No system files were changed


8. No sound assertions on console

IOReg does not show a speaker connected to the front panel green connector. Why?
See Post #1/I. No Sound/3. Front Panel

Because at the moment the headphones are connected to the read panel.
This is the only way I can hear sound on the headphones, as the from connection is jittery.... Any solution?

1. Output devices are listet in Sound Pref Pane but no sound is played. Plays (e.g. Spotify) claims “Can’t play current song”. Spotify can play the song when i switch to my sennheiser usb headset output.

2. 10.12.6 / GA-H170N-WIFI / F20 / i5 / GTX1050

3. audio_cloverALC-130_v0.2.commnand.command (terminal output attached)

4. Iojones attached

5. Attached

6. not installed

7. couldn’t find any messages containing “Sound assertion” (see screenshot)

8. Screenshots attached

9. not installed

10. attached

11. bose companion, tried all ports (currently the green one on the back)

thank you!
