Are you on Linux? Does it use OSS or ALSA? (you can find out by running pjsua, then issue "cl" command and see the name of conference bridge's port #0). Normally playfile should play fine, and most people who are having problem with audio only encounter the problem with pjsua (or when the conference bridge is used). So if you're having problem with playfile, that's a new problem and it's quite bad. :) Can you probably try with opening the sound device on different clock rate? cheers, -benny
