[HELP] Sound card - Realtek ALC662 rev1 [82801l ICH9 family hd a c rev.3]

[HackMan85]

alright, try this one.

 

hackman-s2-rev1.zip

Back:

audio without a microphone

Front:

nothing.

@HackMan85

Try this:

Back:

Audio with microphone

Front:

Nothing.

it's really weird your front connectors are not working.   but it works fully well in windows....

 

anyway, upload your DSDT.aml.  we'll try to enable loading of appleHDA.kext through DSDT instead of using HDAEnabler.   i just want to see the "behaviour" of appleHDA.kext.  

[HackMan85]

I also peels pinconfig from Windows, just in case there is an error in Linux.

[b1gdadd1]

ok, put this DSDT.aml into your /Extra folder.   remove HDAEnabler in boot.plist.   reboot and upload the usual dump files please.

 

DSDT.aml.zip

[HackMan85]

Now pinconfig is present in ioreg but the front audio and microphone will not work, is already one step ahead.

[b1gdadd1]

does your hdmi work? with mirone's kext all your back connectors work, correct? but not with mine? (see, i'm just a noob  )

[HackMan85]

I downloaded and tried the kext to mirone and work the same way;

Back: hdmi ok, ok microphone, audio ok

Front: no

[b1gdadd1]

let me clarify that mate.   with both kext (mirone and mine), all back connectors work but still no front connectors work.   that is with appleHDA.kext enabled through DSDT patch, correct?

[Mirone]

make sure in your bios

is activated the front pannel HD.

 

HD Audio Not AC97.

[HackMan85]

is set to "auto" but now that I've enabled it does not work anyway.

with the dsdt of b1gdadd1 now in ioreg item appears pinconfig, now try again with all the kext that you have posted, and perhaps has something to do also the setting of the bios.

@HackMan85

try this:

AppleHDA_for_ALC662_V2.zip

[HackMan85]

only hdmi.

for me nothing is simple to resolve.

[Mirone]

@HackMan85

try this: http://www.sendspace.com/file/xynguz

[HackMan85]

Again only hdmi audio.

[Mirone]

try this:

AppleHDA_for_ALC662.zip

[HackMan85]

Again only hdmi.

[HackMan85]

Again only hdmi.

[Mirone]

@HackMan85

try this:

AppleHDA_for_ALC662.zip

[HackMan85]

Now works the audio and the microphone on back and the hdmi, doesn't work the frontal audio and microphone.

[Mirone]

In my opinion

there is something wrong with your audio front.

The kext seems to work well, look in your Bios.

[HackMan85]

On windows and Linux works correctly.

Can you give me some link to understand how to edit the files? so I experience.

[Mirone]

No Idea.

try this:

AppleHDA_for_ALC662.zip

[HackMan85]

I think that I can not expect more from this kext, maybe I'll try to help my dsdt to try to get it to work by adding a few patches, tomorrow I will open a topic.

[Mirone]

There are no patches to operate audio front.

I do not know. Your attempt is the kext.

this is your current pin config and path map:

PINCONFIG:
21471c60 21471d40 21471e01 21471f01 
21871c10 21871d90 21871ea1 21871f01 
21971c80 21971d90 21971ea1 21971f01 
21a71c20 21a71d30 21a71e81 21a71f01 
21b71c50 21b71d40 21b71e21 21b71f01

PATHMAP:
Mic at Ext Rear      0x18 > 0x0d > 0x03 (24>13>3)
Mic at Ext Front     0x19 > 0x0e > 0x04 (25>14>4)
Line In at Ext Rear  0x1a > 0x23 > 0x18 (26>35>24)
Line Out at Ext Rear 0x14 > 0x0c > 0x02 (20>12>2)
HP Out at Ext Front  0x1b > 0x22 > 0x19 (27>34>25)

 

this should be your path map (more or less ):

Inputs:
Mic at Ext Rear 8-35-24
Mic at Ext Front  8-35-25
Line In at Ext Front 9-34-26
Outputs:
Line Out at Ext Rear 20-12-2
HP Out at Ext Front 27-14-4 (or 27-12-2)

 

 

@hackman85:

 

have you tested front mic and headphone with windows or ubuntu?

 

 

According to above pathmap, but still not work.

 

Many error msg in dmest:

And not anyone devices are listed in the System Preferences/Sound/Output|Input

Do I need a patched dsdt.aml in /Extra?

 

New AppleHDA.kext is attached.
