Last evening I decided to watch some music and tv on my ipad, I of course have done this regularly without event but last evening I noticed there was no sound coming from the speakers. I'm on IOS 6.1.2 and haven't had a problem being on this since it became available?, the strange thing is when I plug my headphones in I can hear sound ps and alter the volume with the volume toggle??. On pressing it now both up and down nothing happens at all. I have checked the facility when you double click home button and scroll to the right of the screen , the volume toggle isn't showing, I haven't altered anything in settings?, I have read this is a common issue but I find it baffling. If I click the sounds tab in settings, then ringer and alerts tab, the volume toggle can be moved up and down, but nothing what so ever from the volume toggle. I have tried cleaning the headphone jack and docking jack, no improvement and rebooted the ipad, please help if you can thanks.
