In my experience this happens on systems where a given sound chip has
a fixed sample rate. -Dplug tells alsa to do a smaple rate conversion
in software I beleive.

In my experience the #1 reason this happens to me is that some other
software has grabbed the sound chip. Check that other sound daemons
aren't running and that no other Alsa apps are busy, stuck, crashed,
etc.
