The -r and -e options are device properties, so they must precede the -f option that adds the device. Try this: rcctl set sndiod flags -e s24 -r 96000 -f rsnd/1 -m play This is because there may be multiple devices with different parameters. See the last paragraphs of the DESCRIPTION section of sndiod(8).
