Nice work. If it does not work taking from CD player jack to GPIO, you could connect to the bottom of TB PCB, to the TB’s SPDIF jack’s PCB contacts.
Look forward to your results.

Thanks. It works with the small coaxial cable looped around to the TB SPDIF input on the outside.For now I will live with setup. Thanks again for your help.
