IOS apps are losing all sound!??
in Tech Support
Hi, I'm getting increasing reports of my iOS apps losing all sound with seemingly no fix, leaving my customers with a silent app that they just can't fix! I've been through every 'fix' I can think of with them, restart app through recent apps list, hard reset iPad, uninstall and reinstall app, even restore iPad with iTunes!! But nothing has brought their sound back 
Can anyone shed ant light on this rather worrying issue?
Thanks
Wayne

Look in your ipad settings and go to "Use Side Switch to:" and if it is set to "Lock Rotation" your sound can be muted even though the volume indicates it is fully up. The link has images that will help.
