Hervé,

 

Install done :-P , all seems to works fine

I've just replaced your ssdt with Jack Lo i5 2520M ssdt, boot is fast and no sleep issue ; update in 10.9.4 in progress

Now, I just need to setup my broadcom wifi card

Thank very much and have a nice evening

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
