Are we allowed to use default system sounds in third party apps?

Question

Are we allowed to use default system sounds(like message ringtone) in third party apps?

Answer 1

No. From the multimedia programming guide

Note: System-supplied alert sounds and system-supplied user-interface sound effects are not available to your application. For example, using the kSystemSoundID_UserPreferredAlert constant as a parameter to the AudioServicesPlayAlertSound function will not play anything.

If you were allowed to use them, there would be an API for it.

Answer 2

If you say:

"can we access chord.waw and play it directly"

my answer would be:

"no, there's no guarantee that the file actually exists on target machine, and I'm not even diggin into rights or other legal implications - if appliable".

If you say:

"can we emit the default system sound bind with a system event (eg: modal popup) ?"

my answer would be:

"Yes, system sounds are there for this reason, so our application will be coherent with the target system standard behaviour - and legal implication about rights on sound files would be entirely out of my application scope"

Forgive my bad english.
