<font color='#000000'>Hi Welcome to the forum
If I understand you correctly you dont have enough optical
inputs on the back of your receiver and now have to disconnect the optical cable then plug in the one that is on the source you want to use? If this is the case then the
Sony SBD-30 3x2 Optical Digital Audio Selector can help
you. There is also the Sima SCS-4D It has auto switching
and can convert a optical input to coax. You would be in fine shape with this one if your receiver has a digital coax input
Hope this hepls
