We've had our fire tv stick for about 7 months now and all of the sudden the audio won't work when we turn the tv on. Sound works fine with all other apps on the TV. The first few times restarting the device would resolve. Then I would unplug/plug back in, or try a different HDMI port. Today I've tried all three methods and it's still not working. It used to be intermittently but it's been a daily issue the last week. Has anyone else experienced this?
I'm sorry about the issue you're having with your Fire TV Stick.
From what you described, it sounds like you may need to try a factory reset for your device.
Before you begin, keep in mind that a factory reset will remove all content and data on your device. This may include some of your in-app purchases, so you may want to check with the app developer for information about their in-app policies. If you have parental controls settings enabled on your device, you'll need to turn them back on again as well.
However, movies, TV shows, and apps you've purchased from Amazon are all saved to your account, and you'll be able to access them again after the reset once you re-register your Fire TV.
To reset your device:
1. Select Settings from the Fire TV menu. 2. Select My Fire TV and then scroll to the bottom of the list. 3. Select Reset to Factory Defaults and then confirm you want to reset your device.
