I made another attempt. It turns out the only change required is to specify the pcm as "plughw:1,0" instead of "hw:1,0", for reasons I don't really understand. I placed this in /etc/asound.conf. Using this extra alsa device, I can now use shairport-sync to upsample all my incoming Airplay streams to 88.2 kHz, which is what my external DAC requires.
