"Connection refused" is the message you get when trying to
use a pulse client program without having the daemon
running.

The "Failed to set hardware parameters: Operation not
permitted" is an encrypted message, and means that
pulseaudio couldn't open the device for 16-bit samples,
because the device only supports 32-bit samples. You seem to
have an older version of pulseaudio. Since 0.9.8 pulseaudio
has supported 32-bit samples, so you'll have to upgrade to
at least that version.

An unrelated note: you seem to have made the decision to run
pulseaudio as a system-wide daemon. That is not generally
recommended way to run pulseaudio, it's only for the cases
when the per-user way just doesn't cut it. This isn't a
fatal mistake (if it's mistake at all, I don't know what
kind of setup you actually have/need), and you don't
necessarily need to fix it. Some information on this matter:
