we just got a UN82RU8000FXZA and have 3 devices plugged into it. The Xbox sounds perfectly fine but the FireTV stick and the cable box have low audio. Increasing it from volume level 20 to about 70 doesn't make a difference. The Xbox sounds perfectly loud at 15. I have changed the audio setting to "best available" and stereo on the fire stick. Have tried various different settings on the tv such as amplify but have had no success. I changed the hdmi inputs around and still have the same result. Any other suggestions I can try? All the same devices sounded fine with my older Samsung 8000 series TV. Thanks in advance.
Thank you for taking the time to respond and for your suggestion. That might indeed be the case with the cable box but the firetv stick is plugged straight into the TV and the audio is very low. Unfortunately, the firetv is the device we use the most too.
