Take a read of QA1016: <http://developer.apple.com/qa/qa2006/qa1016.html> Also, TN2102, if you haven't already: <http://developer.apple.com/technotes/tn2002/tn2102.html> However, I would urge you not to mess around with the user's volume control, even you think it is an "emergency"---the user may feel very differently. Your application should play an alert sound, and trust that the user's system output volume and alert volume are correct for what they want to hear (although, I have no idea what your application does; but in the general case, messing around with user settings when they don't expect it isn't good). -Phil _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
