E7440 10.11.4 Sound issues

[Hervé]

Do you use a SSD or HDD? If SSD, did you activate Trim? It's probably safer not to... Enabling Trim also caused same systematic KP on my E6440 after basic upgrade to 10.11.4 through Apple menu (no Recovery or Thunderbolt update).

thanks for that tip .. 

 

Well OSX 10.11.4 is running ok (i did not install the recovery update) .. sleep works, audio works when it wants too.. sometimes it will stay, sometimes its there briefly and then stops working. other times the Audio hardware is not detected.. 

 

Would editing DSDT or SSDT files to accomodate the audio be better then relying on kexts? 

 

Are you using your own DSDT/Config.plist?

 

Also have not tried HDMI output yet ..

 

just tried it.. none of the HDMI Audio outputs appear to work.. video is great tho

 

I did a new install with 10.11.4, just replacing VoodooPS2Controller with ApplePS2Controller found in the Updates section. No issue with KP, audio and HDMI audio all working.

Are you using your own DSDT/Config.plist?

Yes using my DSDT and SSDT i created back when El Cap was first released.. (maybe needs an overhaul) Also using the config.plist from your bootpack.

 

I did a new install with 10.11.4, just replacing VoodooPS2Controller with ApplePS2Controller found in the Updates section. No issue with KP, audio and HDMI audio all working.

 

Hmm i may need to update the HDMI and Display Port kext files then (use the ones on the Vietnam tool perhaps). 

 

at the moment not overly concerned with HDMI audio.. Oh system does not freeze or crash when plugging in or removing HDMI  so i am stoked about that,, it also detected the TV i plugged it in to so again pleasantly surprised.

 

r.e. trim support..  most modern SSD's i.e. the Samsung eve series have their own internal Trim operations, that way OS does not need to be concerned about it.  Not sure if the LITEON SSD that came with the Dell has internal Trim.. but hmm

[Jake Lo]

No need to use the VietnamTool for HDMI, it's already patched in my Config file.

Trim is also enabled in the Config, so no need to use the command Trimforce.

[Sorcerer]

Hmm not overly concerned about trim. 
 
Ok so why would HDMI audio not be working for me ???

[Jake Lo]

Issue could be with your custom DSDT. Did you patch it for HDMI audio ( renaming B0D3 to HDAU) and adding _dsm?

[Sorcerer]

Honestly i can not remember.. it was patched almost 12 months ago when 10.11 first came out. so likely not as i used the Yosemite guide to patch it..  which was outdated at the time.. However i did make a fresh dump from clover last night. so if need be i can patch it.. 
 
is a guide available for 10.11.x?

[Jake Lo]

I assume you are taking about pokenguyen's Yosemite guide?

 

Patch with this. Afterward do a search for B0D3 and rename all to HDAU. Save file

# for HDMI audio

into method label _WAK code_regex B0D3 replaceall_matched begin HDAU end;
into definitionblock code_regex B0D3 replaceall_matched begin HDAU end;

# inject "hda-gfx"="onboard-1" into HDAU (B0D3 originally)
into method label _DSM parent_adr 0x00030000 remove_entry;
into device name_adr 0x00030000 insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
    {\n
        "layout-id", Buffer() { 12, 0x00, 0x00, 0x00 },\n
        "hda-gfx", Buffer() { "onboard-1" },\n
    })\n
}\n
end;

into device label B0D3 set_label begin HDAU end;
into method label SBCB code_regex B0D3 replaceall_matched begin HDAU end;

HDMI audio will work with:

1) patched AppleHDA kext

2) DSDT patch

 

For patched AppleHDA kext, you can use either the attached 10.11.4 patched kext (replace the vanilla AppleHDA kext in /S/L/E) or use the HVT ALC292 patch, then repair permissions + rebuild cache.

Patched_AppleHDA_ALC292.kext.zip

sudo chmod -Rf 755 /S*/L*/E*
sudo chown -Rf 0:0 /S*/L*/E*
sudo touch -f /S*/L*/E*
sudo kextcache -Boot -U /

`

For DSDT Patch, check that your DSDT is set as follows:

      Device (HDEF)
      {
           Method (_DSM, 4, Serialized)
           {
                If (LEqual (Arg2, Zero))
                {
                    Return (Buffer (One)
                    {
                         0x03
                    })
                }
                Return (Package (0x10)
                {
                    "layout-id",  // specific to HDEF for patched AppleHDA
                    Buffer (0x04) // specific to HDEF for patched AppleHDA
                    { // specific to HDEF for patched AppleHDA
                         0x01, 0x00, 0x00, 0x00 // specific to HDEF for patched AppleHDA
                    }, // specific to HDEF for patched AppleHDA
                    "AAPL,clock-id", 
                    Buffer (One)
                    {
                         0x01
                    }, 
                    "built-in", 
                    Buffer (One)
                    {
                         0x00
                    }, 
                    "AAPL,current-available", 
                    0x0834, 
                    "AAPL,current-extra", 
                    0x0898, 
                    "AAPL,current-extra-in-sleep", 
                    0x0640, 
                    "AAPL,device-internal", 
                    0x02, 
                    "AAPL,max-port-current-in-sleep", 
                    0x0834
                })
                DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                Return (Local0)
           }
      }

and

       Device (HDAU)        
       {
            Name (_ADR, 0x00030000)
            Name (BARA, 0x80000000)
            Name (TBAR, Zero)
            Name (TCMD, Zero)
            Name (MODB, Zero)
            Method (_DSM, 4, NotSerialized)
            {
                Store (Package (0x02)
                    {
                        "hda-gfx", 
                        Buffer (0x0A)
                        {
                            "onboard-1"
                        }
                    }, Local0)
                DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                Return (Local0)
            }
       }

Yes Pokenguyen's yosemite guide. 

 

do not have the time to sit down and go through the guide now, but i'll attempt it when i have a few hours to spare later on. 

 

Hopefully patching the DSDT will also fix the intermittent Audio issue (sometimes audio not working at all (no device detected) and sometime works then stops after about 4 seconds)..
