Thanks for your support (and sorry for my english, I´m spanish)
The configuration of the computer is ok with the Premiere. I forget to say I have a black magic graphic card.
I´m trying with the default player in the preferences and the option Process audio and video also in the preferences (General), and the sound in the source monitor seems to be ok… but now I have lost the sound in some sequences…
What a mess
