Coincidentally just looking at the sndplay.c file right now...
Can this be the cause of the pops and clicks on macoscx?

   #define BUFFER_SIZE 256
#if WIN32
   /* this setting from Scott Middleton (actually used 8096) */
   #define BUFFER_SIZE 8192
   #define BUFFER_SIZE 4096

(Why so small default buffer on macosx?)

Perhaps using the -bufsize option for sndplay helps?
