Anyone else with no sound in Mail?
I recently performed an upgrade of OSX Mavericks to Sierra on my iMac. For this, I did a so-called 'clean install'. I also then made some organisational changes to my external disks. The result has been disapointing, since I now seem to have more bugs and annoyances on my machine than I ever did with Mavericks.
One particular problem I've now spent ages trying to fix is the complete loss of 'alert' sounds in Apple Mail. I use a pop e-mail account (not from the standard list) which I've fully configured to more-or-less the same as I had in Mavericks, the latter which worked just fine. But now in Sierra, none of the 'alert' sounds that you can configure to automatically play when mail enters the inbox can be heard. There's just dead silence. The same is true of the short expediting 'roar' you normally get in Mail (when you've configured for it) when you send some mail. I'm referring here to the 'New messages sound' and 'Play sounds for other mail actions' settings in Mail > Preferences > General.
I have, of course, checked all the settings in the Sound section of System Preferences. In fact, I've thoroughly checked any and all configurations on my Mac that might conceivably affect sound output. But to no avail. However, all sound associated with the playing of music via iTunes is fine. Incidentally, there are no plug-ins or extensions installed.
Curiously, if I choose and set a new sound into the 'New messages sound' box, that sound will be momentarily heard (this is normal). But it just doesn't then happen whenever it should, namely when I receive an e-mail. And neither does the Send 'roar' sound that you normally get in Mail.
I've explored a few system files, hoping for some clues to this. In System/Library/Sounds, all the built-in short sound effects are there, such as Basso, Blow, Ping, etc. But if I look in Library/Audio/Sounds, the folder is empty (including its Alerts and Banks sub-folders).
I've done several restarts of the Mac into Safe Mode. I've of course downloaded all updates for Sierra. I've also used Disk Utility to run a repair on the Sierra volume, but it's not reported finding anything out of place. Can't see there's much more I can do. Anyone else had this problem since moving to Sierra?
In Mavericks, I got used to the 'in' and 'out' sounds in Mail, over time finding them very useful. Their current loss makes Mail less slick to use now. I need to know why I'm not hearing them and to find a way of getting them back.
