Music - connecting FC5 machine to home stereo

[Peter Horst <phorst@xxxxxxxxxxxxx>]

I'm connecting to an FC5 machine via PuTTY and playing mp3s stored there 
using "orpheus," an ncurses-based player.  Is there is a "hi-fi" way to 
connect this Linux machine to my stereo (an Onkyo TX-SR600, if it could 
possibly matter)?  I know there are various products that connect a 
Windows machine to a stereo via USB (e.g. "HiFi Link" etc.) - is there a 
Linux version of the same?  Not a big deal, of course - worse comes to 
worst, I can just use a minijack-to-RCA splitter.

Thank you.
