Evolution Mail program for Ubuntu doesn't play sound upon receiving new mail

Evolution Mail program for Ubuntu 9.10 doesn't play sound upon receiving new emails.

The box is checked, but only a notification overlay appears upon receiving new mail. If I'm away from the computer, there's no audible tone to indicate getting new mail.

I've overlooked this issue for some time and am now determined to figure out why the sound is not making it to the speakers.

I've also noticed that Evolution's Mail Notification Plugin is unable to play OGG files.

Install mail-notification-evolution. In a terminal, type:

sudo apt-get install mail-notification-evolution

Then if you're using Ubuntu 9.10 (Karmic), create symbolic links from Evolution 2.26 to 2.28:

sudo ln -s /usr/lib/evolution/2.24/plugins/org-jylefort-mail-notification.eplug /usr/lib/evolution/2.28/plugins/
sudo ln -s /usr/lib/evolution/2.24/plugins/liborg-jylefort-mail-notification.so /usr/lib/evolution/2.28/plugins/

Restart Evolution

From the Ubuntu Desktop top left menus, click Applications -> Internet -> Mail Notification

Now you should see a mail envelope indicator applet in the applet tray top right of Desktop. Right click and select Properties. Now you can add your account. Choose Evolution and select your INBOX to monitor.

Cheers!
