Thanks for your reply,
Try increasing the hw.snd.latency sysctl:
Going from 5 to 10 doesn't change anything (actually, it seems worse on the
file I tried). So the mystery still stands...
Note that the micro-interrupts don't occur always at the same timestamp in
the file which is playing.
If I play one, let's say 3 times in a row, sound may drop around the same
moment each time but not necessary...
Just thinking out loud here, but maybe you have some non-standard HZ

I'm not quite sure I understand what you're thinking of. Anyway, I haven't
changed any defaults :
% cat /boot/loader.conf
