Comment (by blurbdust):
After doing some testing, the device actually upscales from 24 bit to 32
bit int when doing a 32 bit capture in the vendor's software. I will be
staying away from 32 bit capture from this device to avoid the upscaling.
As for the requested updates within ffmpeg, if 32 bit int is too niche,
then I suggest upping the limit to 24 bit int instead. That would change
the suggested line update within the patch to `+ { "sample_size", "set
audio sample size", OFFSET(sample_size), AV_OPT_TYPE_INT, {.i64 = 0}, 0,
24, DEC },`.
