Hi,the digital audio output in both my Xiaomi Android tv & DVB-S set top box are coaxial. The DAC has only one coaxial input & one optical/toslink input.There is a switch to select either coaxial or optical.The optical input slot now has the blu ray player optical cable connected.
Is there a way to connect both coaxial outputs to this single coaxcial input in DAC ,preferably activating one coaxial spdif coaxial cable (with a 2 way switch) at any one time.

I came up with an idea but uncertain whether it will work.wire up Rca jack socket connectors with a RG 59 or RG 6 coaxial cable & connect a 2 way switch in between the two spdif out signal.The other end connects to an Rca plug.Its just like a Y cable but with a two way switch.
Do you think it is the right way or is it risky? Can the DAC be modified to add a Coaxial input.I don't want to damage the Tv.
If you guys have any other better solution ,please tell me .Thank you.
