Here's the output of aplay -l:

First command works if I change "default" to "sysdefault" and doesn't underrun:

Anyway, you have just solved our problem. Looks like adding the -D with the hardware name from aplay -L instead of hw:x,y or not using -D (if we only have one card, like in the PCM1754 setup) makes it work perfectly. How is it different to use the -D with sysdefault:CARDNAME? Thank you very much
