As an alternative you could also turn denormal handling off and flush to

The bottom line is really quite simple: if your
app is to run on a PC, use floats.
There are some very good reasons why floats were chosen as JACK's default audio
type.
I agree with that conclusion. Just don't forget about the denormals
issue on Intel (has this been mentioned in this thread before?).
However, it's easy to work around this by adding a small amount of noise
where necessary.
