Curiosity got the better of me. I plugged an audio cable from an old casio lcd tv headphone socket into the RCA's but leaving the cd changer din in place.

The head unit still displays the cd details but the audio from the tv came through the H/U with no problem.

Admittedly it was only on one channel but I think the audio jack on the tv is mono anyway. It seems as long as a cd is playing in the changer the H/U will stay in cd mode despite the different audio feed.
I guess the principal will be the same when connecting from the mobo. When my pc gets delivered I'll try it and let you know. Unless, of course, in the mean time someone else in here knows different.
