I started using desktop notifications from Gmail and although they work generally ok, I get no sound.
I tried this on Franz 4.0.4, on Wmail 1.3.1, on Firefox 49 and on Chrome 53, using Ubuntu 16.04.1. I know that I can use a notifier plugin on Firefox but what I want is to make the desktop notifications work (so that I can use Franz). Any ideas?
I couldn't find anything anywhere that stated that Gmail Desktop Notifications provided audio notification. (Although it appears some expect it.)
One possibility to obtain the results you want would be to use an extension called Checker Plus for Google Chrome allows you to receive desktop and audio notifications for Gmail. This functions even when the Gmail window is closed, making it a handy tool for keeping track of new messages outside of the Gmail app (In Franz for instance?) it can be downloaded free from the Chrome Web Store so you can try it out without much risk. Once installed, you need to log in to your Gmail account to activate it. More information is available at the source listed below.
Note that for this to work a supported browser is required. Here is an excerpt from the Gmail Desktop Notifications help page
You can get email notifications on Google Chrome, Firefox, or Safari when you're signed in to Gmail and have it open in your browser.
Note: You won't see any notifications if you turned off all notifications for your browser.
Open Gmail. In the top right, click Settings Settings. Click Settings. Scroll down to the "Desktop notifications" section. Select New mail notifications on, Important mail notifications on, or Mail notifications off. At the bottom of the page, click Save Changes. Note: If you use inbox categories and turned on notifications for new mail, you'll only get notifications about messages in your Primary category. If you turned on notifications for important mail, you'll get notifications for everything marked as important.
