Audio reading

Dear All,
I have again a problem with audio tracks reading threw banshee, rhythmbox or totem.
The sound is interrupted, same as I had posted a few weeks ago.
Every format is same,wav,mp3,m4a.
Only vlc can read correctly.
I solved the problem last time, with the help of oldcpu, selecting my sound card in the sound menu. What I did again, even ran an alsaconfig in cli.
What could it be ? Codec conflict ?
Thank You in advance

Dear All,
I finally found the bug. My sound card is dead. Peace on her soul.
Thank You
