The sndSsthresh variable, defined as int, overflows with assignment math.MaxInt64 on 32-bit systems.
This currently prevents compilation on arm/32-bit systems, which has to be worked around by defining the variable as int32 or assigning a non overflowing 32-bit value (which is probably the wrong thing to do).
Error:
