@insanelydeepack, How are you doing. I had my audio working perfectly from Mavericks all the way until Sierra. The new IOAudioFamily has broken Audio Master slider control. There is audio max output and mute only from master volume. Apps with their own volume control such as Logic Audio work independently of the master control volume output and work as a master volume control should. Websites such as Youtube with their volume controls work the same way complete output control of volume but independent of Master volume. I have the Realtek ALC282 but my audio device is audio 2.1 (subwoofer) a second speaker. I see in your GitHub you have version ALC282 and gave it a try but no audio output, I think the nodes are different in my version of ALC. I would like to see this audio device make it to the AppleALC project but unsure how to get it there. I am not the original person who created the patch it was AreosJc from the Rogue forums also known as Aeros in the insanelymac forums. EmlyDinesh helped create a PatchAudio persistent kext from Aeros originally patched AppleHDA. He was the one who mentioned you had several files uploaded onto GitHub. I chatted with him today. I am still studying this guide and have not fully grasped it all yet. Could you lend a hand to see if you can come up with something, maybe a different layout, going from layout from 3 to 13 did nothing. It would be great to get this working in Sierra or add this to the AppleALC project to see if this would provide a fix to the master control? I have attached my Codec, Info.plist, Platform.xml and Layout.xml for convenience. Let me know if you can have a look. I even tried Mirone's Audio Patcher v1.6 and both ALC282v1 and ALC282v2 may have worked but I did not have 2.1 audio (subwoofer) working with those patches. I contacted Mirone and he told me I could run his patcher and dump the Info.plist and both ZML files and it would create all the files Patcher creates and although that worked fine I still ended up with a broken master volume control. Mrione may add this to his Patcher on the next release but a lot of good it will do in Sierra. Would AppleALC be any different or is this IOAudioFamily kext related only issue? I would also like to add Spdif if you have any experience with this. My Path Map is the first one "0" in Platform.xml Thanks Edited 11-23-2016: I got SPDIFOut to work finally. Now just need to know if I port my layout3 to layout13 as you did if I can get that issue with the Master Volume Control to work as it did in El Capitan. In Sierra its full output or mute even though the slider does move all the way to the right and left as it should. Maybe some AppleHDA or IOAudioFamily Binary patch needed for Sierra? The source is now available for IOAudioFamily.kext and the readme mentions some changes to the Master Volume Control. card1_codec#0_dump.txt card0_codec#0_dump.txt PatchAppleHDA_SPDIF.kext.zip

Try this: Goto System Preferences then Trackpad. You will see the slider for scroll move it to the right one notch. Two finger will now be working. This is in the readme file that comes with the driver also on the ElanTouchpad thread. Let me know if this took care of the problem. Thanks

Thanks EMlyDinEsH, I tried to put this kext in /Clover/Kexts/10.x and it says it uploads the firmware in Verbose but does not enable the card. I have to have the kext in /S/L/E. I was also concerned that on every boot it is updating the firmware. Is it doing this on the hardware or updating the driver kext each time? If so then great and if not is it such a good idea to flash firmware to the device on every boot? Thanks

Hi EmlyDinEsH Elan :Unexpected magic knock result 0x00, 0x01, 0x14. Elan: FirmWare Version 3884993 Elan: Unknown hardware version, aborting... Its an Asus G51JX-A1 I am sure you need more information than that let me know. Maybe this is not a supported touchpad? Keyboard and Asus key brightness both keyboard and LCD work fine. I was using Rehabman's prior to this. I just thought about this. I am now on clover and use clover to patch the DSDT on the fly. Maybe I need information added to DSDT for the ELan trackpad to work? Thanks EDITED Look at this I am guessing that the RehabMan's package includes your touchpad driver look at this when I load his driver. ElanTech Touchpad driver v1.8.2 beta by EMlyDinEsHMG © 2012. So I need an older driver of yours to get this to work?

Well that even better yet if it install everything in /Extra/Extensions and does nothing to the /system/library/extensions. I'll keep an eye out for the updated drivers as weeks go by. I installed Mavericks on a separate drive then installed that drive on the D830 and it would boot and get to the desktop with a white screen then a black screen and I would actually see some last few verbose messages at the top left of the screen. Desktop never booted. Maybe Darkwake is needed? Thanks

I noticed there was not a AGPM nor VoodooHDA kexts in the Bootpack. Would anyone have that for the D830 with the Nvidia NV140 graphics which is very close to the 8400M graphics card. Is there a way to use EDP without an actual install and just get the packages into a zip or folder? I read in the forum to choose VoodooHDA #3 but any way to get these files without installing EDP? For the AGPM just wanted the section for MAcBookPro3,1 modified for the High and Low thresholds and strip away any integrated graphics in that section. What is the VoodooTSCSync.kext used for? IS the DSDT in the bootpack the most up to date version or is the one from the EDP more updated? Thanks

DSDT is the same as I posted earlier but just added section below which had nothing to do with LCD brightness anyhow. Had to change LPCB to SBRG since that is the device by default in my DSDT. I would have to change all references to SBRG to LPCB and not sure if I need to do that for OSX Mavericks or not?

@EMlyDinEsH, Problem solved from my post above. I'm not exactly sure why I could not get this to work, but AREOS helped me from the fermi freeze thread over at insanelymac. He provided the driver and the DSDT edits which were the same as mine. Was I suppose to enable anything in the driver before using it? Thanks

Yes Volume and DVD play, eject etc.

@EMlyDinEsH, I have an Asus G74SX no Optimus Enabled on this laptop. Nvidia GTX 560M graphics. I am unable to make the LCD brightness change with FN + f5 or +f6. I am using your latest 1.7.2 driver. Running mavericks but also tried on 10.8.3 and it did not work. I don't see anything in console when I hit the keys? I attached DSDT and IOreg and system. log if you could have a peak. Thanks DSDT_IOREG.zip System.log.zip

Does the EDP installer contain the DSDT for the D8xx series laptops and other kexts needed for the post installation? Is there a way I can view the kexts and DSDT before installing the EDP? I want to see if the SMBUS script was added to the DSDT which is needed for OSX 10.7x and 10.8x. Thanks
