No Mail Send Whoosh Sound
In an older thread an answer was given supposedly solving why the "whoosh" sound on sending mail disappeared. The answer was:
"Check Mail>Preferences...>General> ✓ "Play sounds for other mail actions," and System Preferences...>Notifications>Mail> ✓ "Play sound for notifications."
Well, I have all of those settings active and I still get no sound on sending mail.
How about an answer that works?
