eARC/HDMI switch

eARC goes from a smart Sony to a KEF LS50 Wireless II eARC port.  I also want to connect HDMI from a Blue-ray player to that port so I can switch between TV and disc.  The HDMI switch I have does nor pass eARC from the Sony.  Can anyone recommend a switch that can pass eARC on one leg and HDMI on the other.
