Details:

Trying to write audio data to a flac file specifying a value of 24 for the
additional parameter 'BitsPerSample', result in error

error: audiowrite: failed to open output file 'Song.flac': Format not
recognised.

despite audioformats returning

name: FLAC (Free Lossless Audio Codec)
extension: flac
id: 1507328
subformats:
  Signed 8 bit PCM
  Signed 16 bit PCM
  Signed 24 bit PCM

among others.
It succeeds if BitPerSample is 8 or 16.
I tried this on a Windows build with the same result, so I don't think this
relates to my Linux configuration
