I am interested in a solution for S/PDIF input without SCMS detection to USB. The Cmedia CM6610A does support S/PDIF input to USB:
Supports S/PDIF input for 44.1K/48K/96K/192KHz@16/24bit
(96K/192KHz/24bit are available only in USB Audio Class 2.0/High-speed mode)
But sadly, I found no board utilizing that feature, I am thinking about designing a PCB for that chip or modding one existing board. But if I bother to design something, I could just build something completely new, that could support ITTS. Is the ITTS information kept when converting S/PDIF to I2S or would I have to build a custom S/PDIF decoder? Any insight where ITTS data is stored in the signal @Jac?
I found one relatively cheap commercial USB audio interface, that supports S/PDIF in, but it is according to the driver name based on the older Cmedia CM6206, which advertizes SCMS compliance and has lower resulotion. I will keep you up to date, when I receive the unit. B07DGR9M6M is the ASIN, avaible on European Amazon for about 15 €.
