You need to determine what app has control of the sound card.  The
easiest way is to run:

For example, on my system:

$ lsof | grep dsp
gaim      3705 dkelson   15w   CHR       14,3              32928 /dev/dsp
$

No you know the culprit. You could kill it. 

What is the long term solution?

1. Get a sound card and driver that allows /dev/dsp to be opened
multiple times. The Sound Blaster Live card(s) and the "emu10k" driver
allows this. Other cards do as well.

2. If you don't have such luck on the sound card, run a sound card
arbitration and mixing deamon such as ESD (normally for GNOME apps) or
ARTS (KDE) and configure all your sound producing applications to send
sound through that daemon.
