Hi, I'm new here. I'm getting to know the iPad, it's great. Can anyone help with a question please? I've been able to watch movies rented on the iPad on the tv using the apple AV HDMI adaptor, but the sound also goes through the tv. We normally have the sound going through a sound surround system. How could I get the sound from the iPad to go through the amp while the picture goes through the tv? Thanks if you can help.
