try

aplay -v -D hw:0,0 --dump-hwparams --period-time=10000 any44100hzstereo.wav


you need to ask  Florian (author of bcm2835_i2s.c)

1) .periods_min * .period_bytes_min or .buffer_bytes_min seem less than the
size of fifo 
2) are there any timeout loop  which cause hwptr remain unchanged for more than
9ms ?
