BUG REPORT - JRMC28 does not support ALSA Plugin's FLOAT and FLOAT64 formats.
MC's format pulldown does not offer the selections of ALSA Plugin's published FLOAT and FLOAT64 output formats.
.... MC will output whatever the device and its driver support.
Update:
All 6 of the ASLA plugin's published formats are found by the open source aplay test(/dev/zero) CLI dump command.
Being open source, the code is readily available on how to query an ALSA plugin's feature set.
aplay -v -D camilladsp /dev/zero --dump-hw-params
Playing raw data '/dev/zero' : Unsigned 8 bit, Rate 8000 Hz, Mono
