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.
Hmm, I cannot reproduce the problem, at least, dmix + HD-audio. After removing sleep(1), it quits immediately.
Doesn't this problem happen if you use usb-audio with "hw" PCM?
It's possible that the behavior of snd_pcm_drop() of usb-audio is different from others because of URB handling.
