Moderators Jake Lo Posted February 18, 2017 Moderators Share Posted February 18, 2017 Do you have correct layout-id set up in your DSDT? Link to comment Share on other sites More sharing options...
tito480 Posted February 19, 2017 Author Share Posted February 19, 2017 Yes, I am using a folder you upload with Layout-ID 3, I tried with HDenabler3 and I also tried with patching the dsdt file on MaciASL using the Audio Layout-id, its worlking I can hear the audio but after the apple loading all the screen goes black, there is no Kernel Panic only all black even with Verbose mode.

Moderators Jake Lo Posted February 19, 2017 Moderators Share Posted February 19, 2017 Was it working prior to fixing the audio? Have you try connecting to external monitor? Have you try increasing the Brightness slider? Link to comment Share on other sites More sharing options...
tito480 Posted February 19, 2017 Author Share Posted February 19, 2017 No its only works with voodohda but the quality is horrible, theres nothing on sound options, maybe I am making something wrong? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 19, 2017 Moderators Share Posted February 19, 2017 I mean your video, was it working before you add the audio patches. Link to comment Share on other sites More sharing options...
tito480 Posted February 21, 2017 Author Share Posted February 21, 2017 Yes it was, your DSDT is the only I can get the audio working , but the video with intel hd 5500 stops with the rehab patch, is there anything I can do to stop using voodoohda? I tried Applealc, Cloveralc, nothing helped me. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 22, 2017 Moderators Share Posted February 22, 2017 Instead of using the DVMT patch, you should change it in the BIOS. See my E7450 guide under pre-requisites. Link to comment Share on other sites More sharing options...
tito480 Posted February 25, 2017 Author Share Posted February 25, 2017 Ok I set the DVMT to 94MB with grub the video is working perfectly without the Rehab patch. ​Now I used your Sierra 5548_HD5500_Only.zip, I can hear the sound activating on boot, and the AppleHDA_ALC255.kext is loaded, the sound appears to be working but on sound settings I have the message "No output devices foud" Can you help me? I think I'm finally close to solve my audio issue. Finally I make this work!! I forgot to add the layout-id patch on DSDT file. Thank you Jake Lo your help was the only one that make me understand these things. I just need one more help to make battery status work, can you help me? I installed the ACPIBatteryManager.kext but I can't find the right DSDT patch to my Dell inspiration 5558 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 25, 2017 Moderators Share Posted February 25, 2017 I don't think this model need a battery batch to work. Attach your DSDT and I'll take a look. Link to comment Share on other sites More sharing options...
