Media Player Failure When Speakers Not Present

[Kevin Rushforth]

I see it in the system, with an internal ID of 9066884. Once it is 
transferred to the JDK project it will be publicly visible and you 
should receive email notification.

FWIW, I think I've seen this problem in the past. I don't know how easy 
it will be to fix, but at least it will be tracked and we can take a 
look at it. You should should be able to detect this as an error 
condition in your program by listening for a media error. See 
MediaPlayer::onError
