Do you know why I love Linux? Well... there are a lot of reasons, but here's yet another one. You can tell exactly what the thing is doing. I wanted to see what the ogg123 players does/calls when it plays a file. Simple with strace:

strace -f -c ogg123 /usr/share/sounds/KDE_Dialog_Disappear.ogg It gives you the results in a nicely formatted and sorted output even! Way cool.
