I'm having a hard time following. On my 84 the audio and video parameters are all in one menu labeled "AV Parameters" within that menu my settings are as follows;
HDMI -> AMP
V CONV -> ON
RES -> PURE
I did toggle the different options and noticed if I turn V CONV -> OFF then my RES menu is no longer available. At any rate if HDMI -> AMP then it is going to route your audio to your receiver, if you set it to THROUGH it will send it to your TV and in conjunction will automatically change RES -> PURE with no option to change. Your menu structure is a little different on your 94, but I think the fundamentals are the same.
