Modifying a cd player to use as a DAC


Is it possible to add a digital input to a cd player in order to use it as a DAC so you can use another digital source, such as a PC, instead of the transport in the player?

I have a jolida jd 100 which has a 24/96 Burr Brown DAC. I want to play 16/44.1, 16/48, 24/48, and 24/96 2 channel audio recordings from my PC through the jolida. Has anyone ever done this? Do you think I'm crazy? I would put my player under the knife in a second if I knew was possible and if I had some instruction! Would anyone care to help? This could be a very valuable mod to anyone who wants to play music from their PC, or any digital source for that matter, but doesn't want to buy another component.

Non-trivial, but it can be done. Probably requires adding a CODEC chip and some switching logic for LRCLK, BCLK, SDATA.
Sure it's doable but how easy depends on the circuit and the components. The first thing needed is a full schematic.

BTW, I wouldn't bother.
