You have to pass aplay a buffer size which is a multiple of the period 
size. Otherwise underruns are unavoidable. I'm not sure why aplay does 
not choose a matching buffer size automatically, but it's on my TODO 
list. Must be something in the driver.

Those underruns also happen on older kernels, but due to changes in the 
alsacore the underruns are now more visable
