Another simplified way of looking at this in stub code:
{
open_wavefile_for_reading();
open_audio_device_for_writing();
set_audio_device_to_non_blocking_mode();
read_large_chunk_of_data_from_wavefile();
write_large_chunk_of_data_to_audio_device();
poll_for_POLLOUT_on_audio_device();
}
I'd expect this to play the large chunk of data but it returns almost
immediately, only playing a fraction of a second.
I'm not sure whether this is a misconception on my part.
