Comment (by blurbdust):

 I apologize, I grabbed the wrong link from my notes.

 waveformatex
 shouldn't be too device specific since the code jumps to `next` if the
 capture type isn't `refptr_FORMAT_WaveFormatEx`. This at least shows > 16
 is supported by DirectShow and the limit within ffmpeg should be raised.


 {{{
 wBitsPerSample

 Specifies the number of bits per sample for the format type specified by
 wFormatTag. If wFormatTag = WAVE_FORMAT_PCM, then wBitsPerSample should be
 set to either 8 or 16. If wFormatTag = WAVE_FORMAT_IEEE_FLOAT,
 wBitsPerSample should be set to 32. For non-PCM formats, set the value of
 this member according to the manufacturer's specification for the format
 tag. Some compression schemes cannot define a value for wBitsPerSample. In
 this case, set wBitsPerSample to zero.
