my reply.

then assuming you can play audio outside of bb running and assuming in non daw work just playing say a song from a library of songs...
the only conclusions are...

1..a setting in bb or..
(a pic of your audio settings in bb woul be helpfull.)
2..as you say a prob with the loops etc being used...or..
3..by any chance is the pg content your accessing being changed as to bit depth and/or sampling rate.

fyi...i was a reaps user from it coming on the market years ago now and also an early contributor of suggestions...but now as pg's realband has received some interesting upgrades i use rb mainly.
sadly rb is only on pc otherwise i would get a m4 mac mini as well as my pc.
which brings me to a question...when your running reaps on your mac
do you see a line at the top of reaps tracks view showing latency etc etc ? (we get that info on pc.) just curious what info is shown on that reaps top line...and what it says for your mac.
reason being i can compare with my new pc which shows around 4 milliseconds latency. in addition in reaps can you record tracks in the flac format like i can ?? thanks.

happiness.
