I think these two have the same cause. The minimum latency (the minreq or 
period size, essentially) PulseAudio will allow steadily grows while the Pulse 
server is used, necessitating its restart to get it back down to manageable 
levels. ALSA's pulse plugin seems to lie and report that it gives you the 
buffer metrics you asked for, but has a larger buffer behind the scenes to 
deal with the server's out-of-control minimum latency requirement.
