Moderators Jake Lo Posted November 23, 2014 Moderators Share Posted November 23, 2014 Try the kexts and dsdt here. I don't use Clover, but the files are the same just need to be place in different directory. Link to comment Share on other sites More sharing options...
wern Posted November 29, 2014 Share Posted November 29, 2014 Thank you Jake Lo, i tried your kexts and dsdt but no hdmi audio With your files i have a blank screen on the laptop but hdmi video is working, after display detection the internal screen is also working, but no dmi audio can you please upload an ioreg with plugged in hdmi device Link to comment Share on other sites More sharing options...
wern Posted December 6, 2014 Share Posted December 6, 2014 Hm, no one else with working HDMI-Audio on this Laptop? It's the last non working device, and the brightness lowest stage gives me a black screen Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 6, 2014 Moderators Share Posted December 6, 2014 Send me your DSDT and Config.plist, I'll try Clover on my E6520 with NVS and post the ioreg for you. Link to comment Share on other sites More sharing options...
wern Posted December 7, 2014 Share Posted December 7, 2014 So you think that clover is the culprit ?, not sure right now i've loaded yosemite with chameleon with the same result, strange that i've got sound on dock's display-port, maybe an hardware failure on the hdmi output, also no hdmi-sound with ubuntu, i will try it with windows and we will see Link to comment Share on other sites More sharing options...
wern Posted January 2, 2015 Share Posted January 2, 2015 @Jake Lo, in your install guide you wrote "- HDMI Video / Audio (Auto Detection works)" Have you really got HDMI-Sound output working on the NVS-4200 Latitude, or only on the HD3000 model?

Moderators Jake Lo Posted January 2, 2015 Moderators Share Posted January 2, 2015 Yes, HDMI sound works if: Your E6420 only has HD 3000 or Your E6420 has HD3000/NVS4200m, then you have to use NVS4200m. Won't work if Optimus is enabled. Link to comment Share on other sites More sharing options...
