Bluray player has no sound

Bluray player has no sound

I recently got a new amazon firestick but my TV only has 2 HDMI ports and one is for the satellite reciver so everytime i want to watch a bluray I have to unhook the firestick and hook the bluray back in and vice versa ive been doing this for like 2 months no problem but now the firestick is still fine but when i hook the bluray back up it plays video but no sound
