In the 10-15 years I've been using Ubuntu/Xubuntu, I can't say I've seen Pulseaudio working reliably on any machines I've used, and It beats me why a fundamental part of an OS doesn't work 'out of the box' and needs in-depth 'fiddling'!
Linux is thousands of different libraries stitched together. Usually it works amazingly well but if you use Linux you have to be prepared to dig around in configuration settings if things don't work. If you want things to always "just work" you are on the wrong OS.

It's all very frustrating, and I'm now seriously considering searching for a distro that doesn't use the Pulseaudio sound server (and 'yes' I have tried several times reinstalling Pulseaudio and Audacity).
Uninstalling pulse and Audacity won't make a scrap of difference but as a starting point you should initialise the audacity.cfg settings file so Audacity runs at default settings. Please see here for how to do that: http://manual.audacityteam.org/o/man/pr ... tml#stored
Have you tried some of the things mentioned in this topic? Have you tried selecting the (hw) devices in Device Toolbar
so that you get direct access to the devices, bypassing pulse?
If you want to use pulse, have you tried: https://wiki.archlinux.org/index.php/Pu ... _crackling
What are you actually playing? If it's a recording from computer playback you may have sample rate mismatches somewhere. Some audio devices on Linux will only function property at 48000 Hz and do bizarre things at other rates. Pulse should sort sample rate mismatches out in theory but it doesn't always.
