At best, we need a small C code that reproduces the behavior.

Ok here is a small example. It's a modified version of pcm_min.c. Simply press ctrl+c to reproduce the problematic behaviour. on my machine it takes about an half sek to stop with an usb head which uses dmix. Using an sblive card (without dmix) stopps immediately.
