Hi, I'm trying to figure out how to make Amazon content audio work through a mini projector I just got. I'm using the fire stick, and I was able to make Netflix audio work by changing from the English 5.1 to the regular English setting, but I don't have that same option on Amazon content. I have no problems with YouTube. Video is working fine, it's simply audio that is a problem. My set up is HDMI from the fire stick to the projector, and audio is a Bluetooth sound bar paired with the projector. It appears to be simply a setting within Amazon content, but I can't find a way to change it. Does anyone know? Thank you.
