Hi there i need a litle help if it´s possible :) at the begining my dsc 500 was able to playback videos with sound but i don´t know what happend how can i turn it on please ? Thank you.

This is caused by one of two things.
The first thing is that you might have accidentally activated the mute function and as a result, it cannot record the sound of the environment since the mic has been de-activated.
The second and most likely thing is that your mic is faulty and can also not record the sound in your environment.
You can try to restore the default settings and see if there is any change as the mic settings may have been altered but if it doesn't then you have to send it to an expert technician to help you change the mic.
Hope this solution helped you? Please comment if you need more information and thank you for using Fixya.com

Sony DSC-S700 can record voice in video clips but you can listen sound of clip by exporting it to computer and playback there.
Camera has no built-in speaker to playback sound.

You will get sound when you transfer recorded movie clips in your computer and playback in computer.
DSC-S500 Sony Cybershot has built-in mic to record sound but doesn't have speaker to give sound during playback in camera. You need to import movie files in your PC and playback in PC to hear sound.
