Multiple sound

[Nguyen Danh Hieu]

I am sorry for my " not stated question" but I don't really understand your
anwser. I"ll try to express out my problems with my poor English. Each time
when I play  sound, for example, listen to music, If suddenly some
application alerts me so soundcard is blocked and I cannot play sound
anymore. Or It's is impossible to play xmms and mplayer at the same time
etc...
It needed multi-chanel sound. As I use now in FreeBSD virtual chanel sound,
separate sound streams are mixed in kernel and we hear all them at /dev/dsp.
I just want to know can we do something likeable in Linux or not.
Thank you.
