Coverity Issue - Incorrect sizeof expression

The expression "sizeof (kPort_audio) / sizeof (kPort_audio[0])" is suspicious. Note that "kPort_audio" is a pointer and therefore the division will not return the number of array elements which may have been the intent.

Medium Impact, CWE-467
BAD_SIZEOF
