[Lazarus] How to play audio from memory.

Hi All!
Is there any Free Pascal code that can play audio directly from memory?
I would like to be able to play the equivalent of a .WAV file through
the stereo output jack of a Raspberry Pi.
Currently I am able to do this by calling omxplayer with a file name and
volume information. Unfortunately, the latency between starting
omxplayer and the beginning of the audio output is several seconds which
is unacceptable for my application. I can't determine whether the
latency comes from loading omxplayer's executable or reading the audio
file, or both, but if I could have the code as part of the fpc
executable and the audio data already in memory, I believe the latency
will be as low as possible.
Any suggestions will be appreciated.
