Trying to repair NOS Hypex DLCP.

Hi all,

So a year or so ago I acquired a DLCP on clearance, it appears the digital in/out chip is faulty however as I can access the bid through usb but not the usb audio device/spdif in so no audio out.

I've talked extensively with hypex but have got nowhere beyond the above understanding.

If anybody knows which chip is likely to deal with digital audio in, or how to identify which chip this would reduce e connected to, please let me know .

Thanks
