New Apple Trailers App - No iPhone 3GS Speaker Sound

[bac240sx]

Just as the title states, I can't get the new Apple "Trailers" app to output sound via the speaker.

YouTube videos work. So do other QuickTime movies, web videos, etc. I tried multiple trailers and none of them output sound. Speakerphone works just fine as well.

If plug in some headphones I get sound, but in the absence of headphones there is no sound.

Is this working as intended or is it just my iPhone?

I have same issue on iPad 2

I'm having the same problem about no audio/sound coming from the new iOS 5 trailers app. I just checked and I do have sound if using earbuds. That seems weird.

I'm using an iPad 2 and have no trouble getting sound from music, YouTube, etc.
