copied!<p>As bneely said. You need to create an instance variable (or ivar) so that multiple methods can reference the same variable. And as you already know <code>AudioServicesDisposeSystemSoundID()</code> stops the currently playing <code>SystemSoundID</code>. And once you declare an ivar you don't need to declare the variable in each method. So the logical conclusion would be.</p> <pre><code>@implementation ViewControllerClassNameHere{ SystemSoundID soundID; } - (IBAction)beyond:(id)sender { AudioServicesDisposeSystemSoundID(soundID); CFBundleRef mainBundle = CFBundleGetMainBundle(); CFURLRef soundFileURLRef; soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"beyond" ,CFSTR ("wav") , NULL); AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID); AudioServicesPlaySystemSound(soundID); } - (IBAction)Years:(id)sender { AudioServicesDisposeSystemSoundID(soundID); CFBundleRef mainBundle = CFBundleGetMainBundle(); CFURLRef soundFileURLRef; soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"years" ,CFSTR ("wav") , NULL); AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID); AudioServicesPlaySystemSound(soundID); } </code></pre> <p>You also might (will definitely) want to <code>CFRelease()</code> the <code>CFURLRef</code>s you copy once you've created the <code>SystemSoundID</code>(so you don't leak memory). In fact you might consider making your <code>CFURLRef</code>s ivars so as not to constantly copy them. You also likely want to call <code>AudioServicesDisposeSystemSoundID(soundID);</code> in <code>dealloc</code>.</p>
