Custom control point capture sound

[Suna]

While toying with the options available for the 'team_control_point' entity, I noticed the following property:

Warning Sound [Sound to be played when this point is being captured (if warn on capture is set)]

I've tried replacing the default sound with others such as the alarm sound used in manhattan (mvm.cpoint_alarm) but no luck getting it to work. Does this property actually do anything? Or does it require additional entities to function?

Figured it out, only the opposing team can hear the warning.
