Two changes in this section. First we are loading the file "Footsteps.wav". - We are also explicitly setting the sources 'AL_LOOPING' value to 'AL_TRUE'. - What this means is that when the source is prompted to play it will continue - to play until stopped. It will play over again after the sound clip has ended.

The only thing that has changed in this code is the loop. Instead of playing -and stopping the audio sample it will slowly get quieter as the sources position -grows more distant. We do this by slowly incrementing the position by it's -velocity over time. The time is sampled by checking the system clock which gives -us a tick count. It shouldn't be necessary to change this, but if the audio clip -fades too fast you might want to change 100 to some higher number.
