I've not play with a Pi so you'll need to explore and experiment.
In general, if these is latency with alsa, you'll get even greater
latency with pulse.
See the sample asoundrc in servers/linux-outloud for some examples of
what you can do.
Warning: dont just copy it, you'll end up with broken audio.
Use aplay to test, play a simple wav file like so:
aplay -v
that will show you all the processing that is happening, depending on
the sound card etc you may need to tune  the buffer-size etc.
