Ensure that selected device is capable of playing a particular sample format at a particular rate. They have to be supported by either hardware directly, or by "plug" and "dmix" ALSA plugins which will perform required conversions on CPU.

apulse works here like a charm. But my /etc/asound.conf is different (I use soundcard 2 aka index 1 as default):
defaults.pcm.card 1
defaults.ctl.card 1
defaults.timer.card 1
