Problems of Skype that we face

Greetings all, so I am having issues with Skype as the title says. Basically when I make calls I cannot hear anything. Those who I am calling can hear me through Skype but I cannot hear them. I have uninstalled Skype and reinstalled and still the same problem. Not sure if this will help but when I log onto vent people can hear me just fine and I can hear them fine, so I have an idea what is going on lol. Any and all help is appreciated in advance. I have checked all my sound stuff and nothing is muted lol. I should of probably added that in.
