You should run only one PA instance, not two. Run it in the non-chroot
env. Also, you need to make sure that /tmp, /dev/shm and /home are
shared between the chroot and the non-chroot env.

I'd probably not bother and simply use the TCP transport. Enable it
via paprefs in the non-chroot environment, and make sure
~/.pulse-cookie is the same for both envs.
