Straight from the Microsoft documentation, when the Audio Format 16-bit value
isn't 1 (which signifies PCM audio), the SampleRate, ByteRate, BlockAlign, and
BitsPerSample are all format specific and do not follow the same constraints
that normal computation that one might make for PCM formats.

The only restriction I see that still applies for non-PCM data on BlockAlign is
that "software must process a multiple of blockalign bytes at a time". In any
case, a blockalign less than 1 makes no sense at all.

Perhaps these assertions should be wrapped in an if block checking if the
waveform actually contains regular PCM data first?
