Yeah easy for comp>Stereo. Depending on its inputs. I use 3.5 mm stereo plug > a set of RCA plugs which then connect > Stereo. For line back it's pmg or 6.5 mm stereo plug (headphones in my case) > 3.5 mm stereo plug > comp. But for recording is a different matter b/c you need a preamplifier in-between the stereo & the comp to control line input.

Switchable sets of speakers in different rooms is very handy.
