You would just need to install the linux-rt package through Synaptic Package Manager and then
select the -rt kernel when you reboot.
No fiddling required! 

Worth 10 minutes to test I would suggest :-)

Ok, if it's that simple why not...

Tested it. No improvement, sound still stutters and crackles when moving between windows, etc.

Audio stutter and the -rt kernel

Well, I'm sorry to hear that.

I should say at this point that I am nothing more than an -rt fanboy and don't have much
knowledge on the subject. 

So take anything I say with a grain of salt and I would welcome correction from more
knowledgeable readers.
 
I have often wondered whether the mere act of running the -rt kernel will provide a more
responsive system albeit with lower total throughput (and pondered whether it should therefore
become the default desktop install).

Or whether, on the other hand, to gain appreciable benefit you have to:
a) have a workload suited to its purpose
b) tune your system (primarily through nice) to produce benefits.

The single data point that you have provided me with leans to the second position.
(Unsurprisingly)

So to give you some more of my ignorant suggestions ... to address your problem maybe you need
to run PulseAudio with a priority above the default. Potentially that could work on the
standard kernel and/or -rt kernel.

Have you tried nice?

No, I didn't try nice or any other priority tinkering. Mainly because I'm not really
knowledgeable about the fine details. But also because I presume that if this were a simple
case of changing priorities, then the bug could be fixed, but people have worked hard to no
avail (judging by the comments).
