In what way did you try to hook up the audio to the stereo?
One thing I would check is to see if the audio/video cable that came with the ps2 is defunct. Try using the cables from your psOne and see if those work.
Originally you said there was no video. Was there sound when you originally hooked it up?
And last, if you used the RF adapter, then where did you try to draw the audio feed from??? The tv? If it is from the tv, then the problem doesnt lie in the ps2, but somewhere in your connections.
Hope everything works out okay
