I used one twisted pair in un-shielded CAT 5 in my Fire Dept to connect
a radio to an audio amplifier system.
The run was over 100 ft. The audio was tapped at the internal speaker of
the radio at a comfortable listening level.
The other end of the wire went into the aux audio input of a audio
for the $$

Skipp, yes you can get shielded Cat 5. I've used it a few times when
running near
AC fixtures etc.

Don't forget, CAT cables have different twist rates for each pair to minimize
crosstalk between them. If one pair doesn't work, try another.

They make Shielded Cat 5 6, as well as shielded RJ45 ends. Takes a special
crimp tool but it is available.
Also, Belden and other wire manufactuers are making special series of Cat
cables with low-skew design specifically for the purposes of sending Audio
Video down the Cat cables.
Using balanced audio in a broadcast environment, I have on rare occasions
experienced issues with cross-talk between long runs of un-shielded balanced
audio lines. (inductive pickup??) I always wondered if the wires were truly
balanced when that happened.
I prefer to used shielded balanced
