This might be way out there, but check /etc/group
Look and see if you have these entries:
audio:x:29:pulse,timidity
pulse:x:115:
pulse-access:x:116:
timidity:x:123:

Of course if you don't have timidity install, ignore the timidity bits.
It's a little thing but, without permissions, pulse doesn't run. Trouble
