[SOLVED] Distorted sound in video and GUI sounds

[aitor]

Well, distorted sound come back. So, the approach of "corrupted file" was wrong.

I have a good clue now. As skywatch ask me, I tryed analog audio output and... works!

I have this output connected to hi-fi and seems to work.

By the moment, this configuration allow me to watch video but, why can't I hear the audio trough HDMI? I would like to know the reason
