This morning I update my iPad 2 to iOS 7 and when I went to do a call on Skype, they are not hearing me. Is there something wrong with the settings or is it something else?
I have a similar problem. It is not only on Skype, any app requiring microphone access, even if granted, does not work on my iPad 2 after installing iOS 7. Uninstalling Skype did not help either.
You might want to check other apps that use Microphone input to make sure it's not just a Skype issue. It could be hardware failure or an OS issue.
