>>> # One way to generate such a file is,
>>> # ffmpeg -f lavfi -i 'sine=duration=3' -f s16le -c:a pcm_s16le sample.raw
>>> src = "sample.raw"
>>>
>>> # This won't work
>>> # packets = asyncio.run(spdl.io.async_demux_media("audio", src))
>>>
>>> # This works.
>>> cfg = demux_config(format="s16le")
>>> packets = asyncio.run(spdl.io.async_demux_audio(src, demux_config=cfg))
