Ok! Let me leave my feedback.

Intalling CodecCommander attached by lisai in S/L/E the kext is loaded.

Code:
 122    0 0xffffff7f823f0000 0x5000     0x5000     org.tw.CodecCommander (2.2.1) <90 12 4 3 1>

The headphones work good but sometimes I lost the audio after the sleep. When this happen if I plug the headphones and I put the laptop into sleep, after the wake up the headphones work again.

The last kext taken from here https://bitbucket.org/RehabMan/os-x-eapd-codec-commander/downloads doesn't work.
It isn't loaded. I tried several times!

Current version is 2.3.0.

Install latest: https://github.com/RehabMan/EAPD-Codec-Commander

Use debug version.

Repair permissions & rebuild cache. Check for errors during cache rebuild (use DPCIManager).

Check system.log after reboot (you can filter for 'codeccommander').

If everything working, go back to Release version (same procedure).

Hello i was having the same issue, to fix i had to use the command:


Code:
hda-verb 0x19 SET_PIN_WIDGET_CONTROL 0x21


I've different hardware, an ALC233, so this isn't so strange (my codec dump don't have a node 0x25 )


I think that in order to find the correct node it's enough to find in the codec dump:
Code:
Node 'aaaa' [Pin Complex] wcaps 0x40058d: Stereo Amp-Out


where 'aaaa' is the searched node. Maybe someone could verify this?

Hello i was having the same issue, to fix i had to use the command:


Code:
hda-verb 0x19 SET_PIN_WIDGET_CONTROL 0x21

0x19 is the node #, 0x25 was the value to be written (it is likely that 0x20, 0x25, and 0x21 do the same thing). You're doing the same thing that I had to do for ALC283. The significant bit is bit 5 (0x20).

You should add your codec id to the ALC283/ALC255 profile and test.

Downloaded and installed your last built revision of CodecCommander, in the info.plist you have already added my codec id (alc233) to the alc283 profile. However, this doesn't fix the garbled audio.

So i created another profile for my codec and inserted in it this command:

Code:
[COLOR=#000000]hda-verb 0x19 SET_PIN_WIDGET_CONTROL 0x21[/COLOR]

and fixed the stereo output in the headphones

So probably 0x20, 0x25, and 0x21 values do not the same thing ;)

No need to build it. There is a pre-built kext available. Read the README.

For Acer Aspire E5-771-74E7 with Realtek ALC283 (HiDef Audio), the info in this thread helped to fix the problem with my sound quality with headphones. The actual sound was similar to the hollow effect as if the connector had not been pushed in all the way. Somewhat garbled and missing frequencies.

To fix:

[1] Download and install the CodecCommander kext port from RehabMan's site.
[2] Reboot
[3] Enjoy headphone sound.

I've noticed I get occasional pops when there is no audio playing. I need to do more investigation.
