hi Nobele thank you for that information i will give it a try,i dont suppose you have any ideas as to download net flix,got the app from amazon but the kindle won't let me install it
I think I've found the solution.
Use the volume buttons on the side of the device, not the volume control drop down on the screen. I always assumed they did the same thing, but the buttons on the side seem to control the volume within Skype, but the on-screen slider doesn't do anything.
Thank you. Using the volume control on the side of the Kindle is the only thing that worked for me.
