No idea why, but I have no volume on calls, emails, txts etc.
They are all set up with ringtones as they've always been but nothing happens when incoming calls etc.
I can test them all and they work, what is going on?

I changed the OS from V5 back to V4.7 as I had no option for email or an option to set it up. I have mail again now but no sounds.

Has anyone else had this problem, driving me mad, not the end of the world i suppose but...............it is actually!!
