eARC to HDMI converters


I'm trying to use a new Sony TV with eARC with a pre-ARC Bryston SP3 processor.  I think there are devices that take in eARC from the TV and output HDMI to the processor.  I've tried two by OREI, but the processor gets no HDMI input.  Looking for recommendations.

I have no personal experience with this unit but please let me know how it works out for you because I am definitely interested.  I have an Anthem processor I may return to service.

OK, it looks like this is going the wrong way.  It ADDS eARC to televisions which didn't previously have it.  I need to do more research.
