How to bypass prerolling

[Yogesh Tyagi]

Hi,

I tried setting async to false but due to this set caps is not  getting
 called  for audio where the audio format is set. So my audio decoder is
not getting initialized and due to this I hear no audio when I keep async
to false.

Any suggestion?

Thanks,
Yogesh
