ALSA music error

Hello,
I'm getting a pianobar (pandora radio in shell client) ALSA error.

ALSA lib dlmisc.c:254: (snd1_dlobj_cache_get) Cannot open shared library /usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_pcm_pulse.so
/!\ Cannot open audio device

The weird thing is that this error only shows up after everything worked for a while. I always need to restart pianobar to listen to music again. Anyone else having this issue?

I guess I'm the only one that has this problem...
