Underrun happens then driver's playback audio buffer becomes empty before
next portion of samples were written. In many cases it is triggered by
external event like system overload (it is possible if you play huge
movies on slow cpu) or intencive io operations.

um um, 
i think i should trick my /etc/asound.conf file and add, for example a
greater buffer or something, i will read again a little more
i thanks much for your answers
in case you are curious, here is my simple conf
(one week to switch from oss to alsa, but now mix is working - great)

ste@station:~$ cat /etc/asound.conf
pcm.!default { type plug slave.pcm "dmix" }
pcm.!dmix {
        type dmix
        ipc_key 1
        ipc_key_add_uid true
        slave {
                pcm "hw:0,0"
                period_size     2048
        }
        bindings { 0 0 1 1 }
