Moderators Jake Lo Posted January 8, 2017 Moderators Share Posted January 8, 2017 Please post your Clover folder, so I could examine it. Since you're faking with HD 520, try this This one works for me. Make sure you have UseIntelHDMI enabled under Devices <dict> <key>Comment</key> <string>HD 520 HDMI #1</string> <key>Disabled</key> <false/> <key>Find</key> <data> AQUJAAAEAAA= </data> <key>Name</key> <string>AppleIntelSKLGraphicsFramebuffer</string> <key>Replace</key> <data> AQUJAAAIAAA= </data> </dict> this second one is not needed for my E7470. It disables audio with miniDP so I left it disabled <dict> <key>Comment</key> <string>HD 520 HDMI #2</string> <key>Disabled</key> <false/> <key>Find</key> <data> AgQKAAAEAAA= </data> <key>Name</key> <string>AppleIntelSKLGraphicsFramebuffer</string> <key>Replace</key> <data> AgQKAAAIAAA= </data> </dict> Link to comment Share on other sites More sharing options...
Tomba81 Posted January 9, 2017 Author Share Posted January 9, 2017 Sory, i was too fast, problem still there Strange, when I leaved laptop to sleep about 5min. and started, a problem still continue! Possibly i started my laptop to quickly from sleep mode at the first time?? after installed codec commander... Maybe something to do with deep sleep?? I try your proposal! Heres my config.plist config.plist.zip Link to comment Share on other sites More sharing options...
Tomba81 Posted January 9, 2017 Author Share Posted January 9, 2017 Finally, i think i found a solution for this sleep mode issue!? When I put it to sleep mode, and fire up again i need to make 'fast double press' power button, so that the sound stays on! If i press power button only once, sound is missing! a strange problem have to say... It looks like this little trick works so far!? I tried you patch. No go! <dict><key>Comment</key><string>HD 520 HDMI #1</string><key>Disabled</key><false/><key>Find</key><data>AQUJAAAEAAA=</data><key>Name</key><string>AppleIntelSKLGraphicsFramebuffer</string><key>Replace</key><data>AQUJAAAIAAA=</data> </dict> HDMI audio still missing... Thanks anyway! Link to comment Share on other sites More sharing options...
