Hi i tested some versions and the legacy driver one too.
I got the solution partially. Dont know why but changing the audio input from AUTO to HDMI 1 runs perfectly.
I dont know why the audio input fix that but it did!
The problem now is that i cant hear anything from hdmi and through analog speakers its ok.
I have enabled hdmi 1 through alsa audio system screen and i can hear the music from de menu in that screen but when i go back to the emustation frontend the sound gets off.
Im going crazy right now, when i fix something another one comes... Dunno what to do.
Sorry for my english.
