A large FIFO *is* sufficient.  For pourposes similar to yours, 
I have been using for years a modified version of "brec/bplay", 
an old popular FIFO-based stream audio front-end.  Even with 
old, heavily loaded P100 machines, I have never experienced 
any problem working at 41khz sampling rates, stereo.

Given that the idea of splitting SOX into small, specialiced
programs (like netpbm) was discarded long time ago,  I also 
support the idea of adding some circular buffering to SoX!
