This suggests pulseaudio may be running in another user and grabbing the
soundcard, and thus the pulseaudio under your user fails to use that.

A possible culprit is the speech-dispatcher package. Would you please
run the following (when the problem is present) and attach the output
please:

pulseaudio --kill ; pulseaudio -vvvv
ps -fea | grep pulseaudio


Thanks
