How about using src-sinc-best-quality or src-sinc-medium-quality for HiFi Shield to get for highest quality up-sampling?

Please explain step by step, how configure ALSA plugin /etc/asound.conf to get:
pcm_slave.sl3 {
pcm "hw:1,0"
format S24_LE
channels 2
rate 192000
}
pcm.complex_convert {
type plug
slave sl3
}

Please explain, why you don't use resample-method = src-sinc-best-quality or src-sinc-medium-quality?

Soxr provides a audible 'higher quality / accurate' conversion > output. I don't know the exact figures, you'd need to run a audio capture test to compare converters.
