Hy Everyone. English is not my language, please excuse any mistake.
Previously I had problems with a sound card, this is another card, another pc, another topic.
I am in Ascii/Beowulf .... from a week to now sound comes and go randomly. I don't use pulseaudio (previously I used it, but with identical results)
I had discovered that when sound is gone, if I run speaker-test after a couple of minutes sound return. I have sound for some time and after this again its gone.

Anyone have some idea? Thanks in advance.

If random it could possibly be a hardware problem? You could try booting from a live distro of another type and see if sound functions normally. That would rule out hardware I believe. Good luck.
