I installed and configured PulseAudio, just to check it out. While the new system has a lot of potential and will make a fine addition to the next generation of Linux Mint (the Linux sound system is in dire need of an update) it's sadly not ready for prime time in my opinion. Some applications will fail to produce sounds while still others will behave erratically in terms of sound. My advice would be to wait until PulseAudio is further improved and stabilizes somewhat before using it on a primary workstation. If you still want to set it up, I can probably provide some assistance. Good luck.
