No. It makes no difference in that regard. Normally Snd loads about
8192 samples into RAM per reader. And calling the GC won't help,
as I mentioned before.
Loading only 8192 samples into RAM has the effect that the playback
of a sound file is often disrupted : Snd cannot be
utilized on stage (the same can happen with with newer versions
of linuxian software, i.e. play or aplay ... whereas the older versions
worked fine).
If you are using snd-ls (which use the <snd-rt-player> instrument in
rt-player.scm for playback), snd actually buffers 5 seconds of sound into
RAM before starting to play. (I wonder if 5 seconds perhaps is a bit too
much though, since memory is not cheap...)
