Linux+SND

Hello All! There is such a problem: if you have Linux RH7.3 everything would be fine, but there is a depressing glitch: I'm trying to launch the player (xmms), but it gives a message as it wants, saying the sound card is busy... And sometimes it can play about 5-6 songs and display this message. If you try after 5 minutes, it starts playing again. Maybe someone knows what can be done with this, where to look...
