Comment 37 for bug 996906

I have the same problem : sound stops after undeterministic time: from several minutes to more than 12 hours. I'm on a raspberry pi (wheezy raspbian). I tried many combinations of parameters for daemon .conf and default.pa.
I notice that whenever i change the parameters , most of the time the new parameters are not taken into account even after pulseaudio -k and pulseaudio --start, i have to restart my "player" which is chromium and sometimes it even seemed that the change was only effective after a reboot of the RPi.
By the way pacmd alsa-sinks says that the buffer size and fragment size are equal for my RPi sink !! how can that be... so i have no idea what parameter to give to the daemon given that puklseaudio does not accept number of fragments = 1 (?!)
i'm currently running with : number of fragments =10 and fragment size = 10 ms because people adviced to use this on forum but i really dont understand where these numbers come from and if these are a good choice
