I downloaded a free app called ipla it has videos, news etc. in polish. when i play the videos, i have no sound. i can hear everything else on my ipad 2 just not this app. on the videos themselves there's no volume option either. i dont know how to get it to work. the videos play beautifully though. could someone download it and check it out for me please? i emailed their tech support but who knows if i even get a response.
