Multiuser pulseaudio - works for 2 of 4 users

view story

Ok, I'm pulling my hair out here. I've one computer setup for 4 different users (one dwm, 3 on xfce). Pulseaudio is working for 2 users...the dwm and 1 of the xfce users. I can't for the life of me get sound working for the other 2 users!! Users are NOT logged in simultaneously...just one at a time. Here's what I've tried:1. No one is in the audio group (per the pulseaudio perfect setup wiki)2. ck-list-session shows a valid ACTIVE session for each user when they are logged in. ck-launch-session is used for each user (in .xinitrc)3. I deleted the ~/.pulse and ~/.pulse.c ()
