I can't wait new version ! So I try to way to make the sound work. I want v7.0 !!!! Lol
I don't know if it is better or no, but now I have sound but no image !
I have added a line in the config.txt.
hdmi_ignore_hotplug=1
it was just to test quickly. So it is not an hardware or driver bug as I was affraid, but just a config.txt trouble with the default V7.0 installation.
Now I have to find a way to have sound, but also video !!!
