I have my Firestick connected to my projector with an HDMI for the video signal, but I want my audio to come from my 20 year old Adcom Receiver ( no HDMI). Can I use an HDMI splitter to send a signal to the projector and a signal to the receiver with a HDMI to RCA and just use the 2 audio wires? Does the splitter need to be powered type? Do HDMI to RCA jacks degrade the signal? Thanks
