kingxsmoothy Posted April 30, 2016 Author Share Posted April 30, 2016 Yes I'm going to install El Capitan now, going to use the folder you gave me and see if it works. Made a backup of Yosemite. The folder you sent me had working GRAPHICS, WIFI, BLUETOOTH, SLEEP. Did not test HDMI. Only issues were no AUDIO, the brightness buttons did not adjust brightness, but could change it via the system preferences. And finally usb disconnected after wake but plugging SD card and usb devices after allowed them to work. Seems like a better idea to fix an El Capitan install as it is newer.

Moderators Jake Lo Posted April 30, 2016 Moderators Share Posted April 30, 2016 Replace AppleHDA_alc255 if you're installing El Capitan 10.11.4. Replace the DSDT/SSDT with this one. I messed up on the layout-id. It's correct now. 3148.zip Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted May 1, 2016 Moderators Share Posted May 1, 2016 Replace files with these for El Capitan. Remember to run permission fix and rebuild cache. Run the last 2 commands until you see a successful output. Note: remove BrcmPatchRAM and add BrcmPatchRAM2 3148_Elcapitan.zip Link to comment Share on other sites More sharing options...
Takahashi Posted October 25, 2017 Share Posted October 25, 2017 Boot to Clover GUI. Hit F4, this will extract the raw files to /EFI/Clover/ACPI/Origin. I'm assuming you don't have any patched DSDT/SSDT at the moment. Compress the Origin folder and upload it here. I'll try to patch them for you. Once you're in the Desktop, download DPCIManager.app. You should be able to get the device info under PCI List. The config you have does have the audio patches, but you'll need the DSDT and the patched dummyHDA to work. Hey Jake, what patches did you apply to @kingxsmoothy's DSDT? I have the same Inspiron 3148, but slightly different hardware (e.g. I have DW1830 instead of DW15-whatever). files.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 25, 2017 Moderators Share Posted October 25, 2017 No DSDT patches are apply for the wireless/bluetooth combo card. You just need 4 kexts and 1 hotpatch See post 1 & 2 here Link to comment Share on other sites More sharing options...
Takahashi Posted October 26, 2017 Share Posted October 26, 2017 Ah, great! I'm glad I swapped this combo card Can I use your patches on Yosemite as well as Sierra? I was able to extract my ACPI tables and patch the DSDT via Clover (BrightnessFix) in order to get brightness adjustment to work. I will later try to patch the DSDT via MaciASL for brightness instead of Clover, get the audio working via DSDT (AppleALC?), and then try to upgrade to Sierra. I am currently on Yosemite. Thanks Jake Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 26, 2017 Moderators Share Posted October 26, 2017 There are some minor differences between Yosemite's patches and Sierra's, but the majority should work. Link to comment Share on other sites More sharing options...
Takahashi Posted October 26, 2017 Share Posted October 26, 2017 Great! I added the patches and they seem to work with the DW1830. I also want to try rebranding it to an AirPort Extreme card to see what happens. EDIT: I remembered that there is a kext patch by skvo that I can apply instead of rebranding. I'll do that instead. I have one last problem with my DSDT—there are three syntax errors that I cannot get rid of. They are all with these devices called ACD0, ACD1, and ACD2. These devices seem to be sound-related... Hopefully my audio will work once these errors are fixed. I have attached my tables in .dsl format for reference. I used ACPI specification 5.0 with MaciASL to parse them.

Moderators Jake Lo Posted October 27, 2017 Moderators Share Posted October 27, 2017 Use compiler 6.1, no error from your DSDT.dsl file No need to patch for AirPort Extreme, the FakePCIID kext will take care of it. Link to comment Share on other sites More sharing options...
