# cat /proc/asound/card1/pcm0p/sub0/hw_params
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 44100 (44100/1)
period_size: 600
buffer_size: 22050

# cat /proc/asound/card1/pcm0p/sub0/sw_params
tstamp_mode: NONE
period_step: 1
avail_min: 600
start_threshold: 600
stop_threshold: 1445068800
silence_threshold: 0
silence_size: 1445068800

I tried several values, including -n {2|3} -p {256|512|600}

But no way. Would an strace be usefull?
