No, definitely not. On my system, it sounds the same as it has with
linuxaudiodev for quite a while, and the same as it did with sunaudiodev
on my old Sun box at CNRI before that.
*Maybe* there's something wrong with how setparameters() initializes the
audio device. Try this patch and see how it goes:

Hmmm, I just noticed that setting O_NONBLOCK at open() time *does* have
an effect -- I needed to change that write() to writeall() in order to
hear the whole test sound. Uh-oh.
