Hi Doug Wyatt,
Thanks a lot for your prompt reply,
Regards to your answer, i want to tell you one more thing, If i download the file from the network stream and write it into the file and then decode the contents of the file using my decoder which outputs linear PCM data then yes it is playing that on device as well...but the minute i discard that writing it to a file part and yes getting the buffer and sending it to decoder as a input n outputs as a linear pcm and passing it on to AudioQueue for playing it fails to play on device....
this above lines works well on iPhone simulator ....you are right probably...let me need more inputs on floating point issue...you mean to say if the buffer i am keeping it floating on device n then outputs to audioqueue is that causing a problem on iPhone OS 3.0x...
Could you please explain me more on this, since i am eager to know the answer where apis are going wrong...because none of the apis produce me error codes all are having success but no sound to device..
Kindly waiting for your reply,
Regards,
Shailesh

If you are decoding to floating point that would explain the issue; AudioConverter and AudioQueue don't support floating point on iPhoneOS 3.x (but, in the simulator, to interface with the desktop's HAL under the covers, they do).

iPhone or iPod touch device...the code for decoder is decoding the contents ....
