The Monkey Posted January 6, 2009 Report Share Posted January 6, 2009 I want to shoot the audio out of the USB port on my Apple Express instead of the optical out. You tell me how. And none of this "it can't be done" nonsense. Thank you for your assistance. Quote Link to comment Share on other sites More sharing options...
The Monkey Posted January 6, 2009 Author Report Share Posted January 6, 2009 how good are you at firmware programming? I'm the BEST. No, of course not. I have no idea about any of that stuff. I was thinking more along the lines of using some jumpers and all would be good. So not an easy project in other words, eh? Quote Link to comment Share on other sites More sharing options...
grawk Posted January 6, 2009 Report Share Posted January 6, 2009 The real way to do it is to crack open the express, and replace the audio daughterboard Quote Link to comment Share on other sites More sharing options...

cetoole Posted January 6, 2009 Report Share Posted January 6, 2009 The real way to do it is to crack open the express, and replace the audio daughterboard Yes, this has a decent shot of working, cutting the existing traces to the USB jack, removing the audio board, and wiring the usb pins which had been feeding the audio board to the USB jack, in a manner which doesnt completely screw with the USB wiring standards. We know that at least older versions used the PCM2705 for the audio board, so it would be fairly simple on these, but I have heard, though unsupported by photos or anything, that the current expresses use something else. Also, since the thing is sonically welded together, you would have to recase it afterwards, instead of just closing it back up. Well, maybe duct tape would work.
