Removed everything PulseAudio related that didn't get rid of mint-gnome-main, or something like that.
Logged out, back in. Checked if my audio was working using rythmbox. Nope. Checked the volume inside Rythmbox; Volume was raised.
Added volume applet to my panel. Master, raised. Headphone, raised. PCM, Line In, and CD were all muted. Unmuted them one at a time.
Unmuted PCM seems to have fixed the problem. I'm now hearing music using Rythmbox.
Logged in to Hulu.com, played random video, sound.
I guess one of the PulseAudio components either didn't like my setup or something else.
I know I've gone through all the inputs before and made sure such things as PCM and Line In and CD were all unmuted. What a wonky occurrence.
Thanks for all help submitted.
