You must have a configuration problem.  What is the error message?

Do you know if the other apps are using ALSA or if they are using the 
OSS emulation?

In general, ALSA is installed as loadable modules whether it comes with 
the Kernel 2.6 or you install it for Kernel 2.4.  To work correctly, the 
configuration data in: "/etc/modules.conf" must be correct for your 
sound card/chip.  With a distro, this should get set correctly, but it 
is possible that it isn't correct.

You can look up you sound chip here:

http://www.alsa-project.org/alsa-doc/

I don't have a distro and I just did copy and paste from their data and 
it worked correctly.

With some distros or if you are using PAM, there can be issues with the 
sound devices, but that would normally give a different error message.
