I have just upgraded from a Samsung Galaxy S3 to a S4, and I am battling to get audible notifications of incoming emails on the Gmail app.

I get a notification in the Notification Bar, but there is no sound.

I have checked my Gmail settings and have selected the ringtone that I want for the notifications, but it doesn't work.

I had it working perfectly on my S3. I have since wiped the S3 clean so I can't even check my settings there anymore.

Any advice?
