Hi,

I'm trying to fix audio via headphones(very silent and crackling).
I've used AppleAlc.kext(audio inject 3) and speakers/microphone works fine. Just* have a problem with headphones.

Code:
Audio details ALC295:
Audio device: 0x80869D71
Sub Device: 0x10431740
Codec ID:0x10EC0295
Revision: 0x0002
I red that was "common" problem on Linux fixed by
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1648183

crontab script settings:
Code:
#!/bin/bash
hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x67
hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x3000
I've tried to modify CodeCommander and setting Custom Commands without success.
Can some one help me with this ?

Thank you.

Problem with headphones is sound quality* from them.
Audio/Sound from headphones is "cracklinkg" and is very quite/distorted/garbled.
On the highest level it getting worse(you can hear crackling) and it's still to quiet.

"jack sense" works fine, audio after sleep works fine, speakers works perfectly but sound from headphones it's a nightmare.

I've tried to change settings in Audio Midi Setup but no change.

You might take a look at the custom configuration for ALC283/etc and apply to your own codec (you'll need a codec dump).
Also, you should check the PathMap to see that it matches your codec dump.

do you have some guide how to do this?
I see that you have some bash scripts in EAPD-Codec-Commander repo but i'm not sure what can i do with data output from them.

No guide.
Requires familiarity with the HDA specification.
The codec dump for my ALC283 on my Lenovo u430 is on my u430 github project, so with that you can see which nodes are being manipulated by the verbs that are in the CodecCommander Info.plist.
