I have a Yamaha RX-V685 and recently purchased the latest Amazon Firestick. Everything works fine with the Firestick, audio, video but when going back to regular tv the audio cuts out for a second or so and comes back. The receiver has 5 HDMI ports but it doesn't matter which port it still cuts out. I can unplug the Firestick and no issues. I also have 2 game systems plugged in with no issues. I've gone through the manual and searched online but most of what I've found has to do with the Firestick audio cutting out, mine works fine it's the opposite. Is there a setting or something in the manual that I'm missing. My TV is a Samsung. Everything is up to date.
