How to fix the mail sent (whoosh) sound when disappearing intermittently
After updating to the recent Yosemite 10.10.3 my email no longer makes the 'whoosh' sound when I send email. All other Mac system sounds work fine, just no mail whoosh anymore. I thoroughly checked all the sound system and mail prefs and they are set appropriately at default. There are no earplugs or other sound devices plugged in. In fact, there have been no changes to my setup other than software updates. I quit and restarted Mail and rebooted the Mac, all too no affect.
My system: Mac Pro (late 2013) OSX Yosemite 10.10.3
Mac Pro (Late 2013), OS X Yosemite (10.10.3), And an iPad Air 2 iOS 8.3
