 Did you enable the sound server in GNOME?  If yes, then you should
 configure your application to use "Esound" as audio output.
 Alternatively, you can disable the sound server and configure your
 applications to use "Alsa" directly.

 Another option which I'm using is to setup PulseAudio, that works like
 esound and supports alsa apps as well, but requires more work to setup.
