Since one line is ok, it is possible the faulty line is actually on a
"split pair" where (for some portion of the run) it is connected using
different legs of 2 pairs in a cable, rather than both legs of one

It will still have connectivity and work, but if there is any junk
about, you'll hear it (as you have described).
