This is what I get here:

> alsaplayer -d plughw:0 -F 44100 -f 512 -g 3 -r
error on set_periods (13)

I have to set the alsa parameters by hand otherwise the defaults that
alsaplayer selects fail [and even then alsaplayer is trying first with
some weird value for periods!]. Obviously I get xruns because it is not
suid root and does not run with realtime priority. I have to use plughw
because alsaplayer does not know how to deal correctly (apparently) with
multichannel cards, I'm running this on a Midiman Delta 66 (ice1712
chipset).
