Is it normal for it to have more-or-less constant

(sample recordings of the Aeolus organ synthesizer) or ripped from CDs,
so they weren't analog recordings that might have such additional
natural sounds.
TIA.

Try the "test audio and midi" menu item in puredata, with the test
signal on the "-40" setting (or some other low level reference signal
of your choosing). If you get the same low frequency pops and static,
it is your sound card or driver (most likely the card). From your
description it could be a ground loop - does it go away if the sound
card is attached to a laptop on battery power?
