I have a Sumsung tv and firestick pluged into on of the HDMI ports. I just bought an Arc and set it up and plugged it into the HDMI ARC port and the firestick is not working now at all, no on/off, no sound no anything. It was working fine witha samsung sound bar and optical. I can use the samung apps built into TV and the sound works fine though the ARC sound bar just nothing with the firestick.
Help haha
