The advantage of using a sine wave (as opposed to a sentinel value
like 0xdeadbeef) is that sine waves tend to be resilient to audio
processing (changing from int to float, dynamic range compression
etc.) but sentinel values are very fragile
I used the following sine wave:
0x8000,0xda82,0xffff,0xda82,0x8000,0x257d,0x0,0x257d
but the captured wav file has a series of 4 to 5 0x0080 followed by
0xff7f, 0x0080, 0xff7f, and repeats.
