I would like to sincerely thank all of the wonderful iPad experts who assisted me with my sound problem. Last night I finally solved the problem! I had been using the headphones that came with my iPhone. I took another pair of headphones from a cd player and plugged these in and miracle of miracles...the symbol on the screen unlocked and the speakers now work! I am assuming that somehow that internal headphone jack got stuck in the on position and by inserting other headphone jacks it released the switch. I am not tech suave but in my mind that is how to explain this.
Anyway, I wanted to let you know the problem has been resolved and I am so thankful for all your assistance. I know this iPad is older but it has always always been so reliable and just THE BEST. It is the first Apple product I ever owned and I personally will never have anything but Apple products. I am 63 yrs old and have had many pc's as well as in my work environment worked on many pc's, but Apple is far superior!
I have had virtually no problems and when I do, this forum is a life saver!
Again, many thanks and keep up the good work!
