[CMI8786 - Xonar DG, playback] No sound at all

Since I upgraded to UBUNTU 14.10, I finally had to reinstall ubuntu for half actualiazción error, the computer has been moved. Appear either audio controls on the system configuration, but no sound.
Found that:
is using the sound card (Asus Xonar) and not the motherboard, so it appears in Sound settings.
the speakers are on and in correct volumes.
In windows (another partition) still works

And the fact is that they do not try to touch or configuration.
