Laptop Microphone Not working

Ok, so I use a Toshiba Laptop ( L650 ) and the new thing is for the kids to contact their friends via fb video chat. The problem is.......we can see and hear who we are contacting, and they can see us but cannot hear a thing.

Can anybody give me any advice as to how I could fix this problem with the microphone?

Thanks in advance.

Hmmmm, strange........I just did a video call to my daughters Mac Book and she could hear me fine. Not sure if my friend has a prob at her end. She can apparently hear others when they call.

Got me stumped

have they got their sound on mute?

the same with mine iv went into audio settings for the mic and every thing turned up but dont work on fb

Hmmmm, there's works fine with certain others they video call, so can't work out why it plays up when we try

Make sure that both ends of the FB web chat are on the latest version of which ever web browser, Chrome - Explore - Firefox - Safari

This could be the issue. Happens to me every so often.
