CheBoludos Posted March 4, 2020 Share Posted March 4, 2020 I wanted to confirm that I have successfully installed catalina on this laptop, using the files provided by @Jake Lo in this thread and the advice for the touchpad by @marlov the only thing that I couldn't see is change audio output in HDMI.

CheBoludos Posted March 5, 2020 Author Share Posted March 5, 2020 Also found that if i plug headphones (Jack 3.5) sound is not clear, i tried using a alc fix but the script could not be executed, even if i tried to unlock system file system. debug_5864.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 5, 2020 Moderators Share Posted March 5, 2020 Hmm, raw IOReg files is hard too read. Run this with HDMI connected, save, compress and attach the file Link to comment Share on other sites More sharing options...

CheBoludos Posted March 5, 2020 Author Share Posted March 5, 2020 Wow now is working fine, at the end im still pending in getting audio through jack 3.5 headphones, i'll try more when i finish work, thanks @Jake Lo Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 5, 2020 Moderators Share Posted March 5, 2020 ALC Fixup is for enabling audio after wake from sleep. It won't fix the headphone if it's not working to begin with. You could try switching layout-id from 12 to 18 or 55 in your Config file. No guarantee. Link to comment Share on other sites More sharing options...
CheBoludos Posted March 5, 2020 Author Share Posted March 5, 2020 Oh thanks for that, i tried changing the values of layout-id but none of them worked, i noticed that headphones are recognized and when i plug it on it sounds a little distorsion and then nothing. Hopefully someone can find a solution. Link to comment Share on other sites More sharing options...
