Oh, forgot to mention: If you aren't sure about where the problem lies, turn up the volume in alsamixer, then try running this command:
------------------------------------------ $ mplayer /usr/share/sounds/gnome/default/alerts/sonar.ogg ------------------------------------------ (note that you may have to root): ------------------------------------------ $ su # mplayer /usr/share/sounds/gnome/default/alerts/sonar.ogg ------------------------------------------ If you don't hear anything, then I would debug the issue outside of GNURadio to simplify the number of things involved.
