All of a sudden the other day my ipod touch’s internal speaker just decided to mute itself. Either that or I somehow muted it. Couldn’t find how to un-mute it anywhere online but I figured it out. Hopefully this orks for iPad’s as well.
Solution 1: Some people said it was the headphone jack was stuck or something, but all I had to do was (don’t have any headphones plugged in) hold the black button on the top of the ipod to turn it off. Then you hold it again to turn it on and if you go to your music you will see the internal speaker volume is all the way down. Turn that music up!!!
Solution 2: If the above solution does not work someone also left a comment saying that if you hold the Up Volume Button it may magically turn on. (thanks Katie)
Solution 3: Plug it into an ihome or other ipod speaker/player press play, then quickly remove it from the ihome and the slider pops up. Try to turn it all the way down then back up. (thanks Brandon)
