iPhone Podcast Audio Problem

After IOS 6 update and installing the new podcast app, I decided to give a few podcast a try (using 4G and not downloaded). The audio only plays as long the screen is active. As soon as the Iphone goes to standby or if I send the app to background by pressing the home button the audio quits.

I am not sure if anyone else has this problem. Any solutions to this issue. I am running IOS6 on Iphone 4S.
