Programmatically launch the Mac's System Preferences screen -> Sound

Question

Is there a programmatic way to launch the system settings on Mac and have it focus on the sound pane?

If so, is there a programmatic way to have it default on the "Output" tab?

Answer 1

There is an easier way:

NSURL * url = [NSURL fileURLWithPath:@"/System/Library/PreferencePanes/Speech.prefPane"];
[[NSWorkspace sharedWorkspace] openURL:url];
