Assume your pc/soundcard has an Optical IN? Then should jus the plugging in the cable and changing the input source.
Plugged the optical cable into my "optical in", and from the Creative control panel thing, set the Optical In to "Listen to this device" and volume up to 100%.
It's basically another input device like a microphone, so as long as you enable "listen to this device" all should work
I run a Createive ZxR![]()
Hmm, well I'm using on board sound but there is a digital optical port. Plugged it in there and opened the Realtek audio manager program, can't see anything to amend the input source though?
