I got the same error when I switched output devices to USB. And continued getting it after switching back to analog:

ALSA lib pcm_pulse.c:626:(pulse_prepare) PulseAudio: Unable to create stream: Invalid argument

Removing ~/.pulse and restarting pulseaudio made the error go away (still haven't gotten usb audio to work). Restarted with:
/etc/init.d/pulseaudio stop
/etc/init.d/pulseaudio start
