Hi! I understand you’re facing no sound on the WeatherNation app when using Apple TV. I’d love to help you get the audio working again.

To start, can you confirm a couple of things for me?
- Are you experiencing no sound only in the WeatherNation app or in other apps on your Apple TV as well?
- What model of Apple TV are you using?
- Is your Apple TV connected to speakers or a TV directly? And are you using HDMI or other audio connections?

Meanwhile, here’s a simple checklist we can follow to troubleshoot:

1. Check TV and Apple TV Volume & Mute
- Ensure your TV volume and Apple TV volume (using the remote) are turned up and not muted.

2. Restart Apple TV
- Go to Settings > System > Restart on your Apple TV to refresh it.

3. Check Audio Output Format Settings
- On your Apple TV, go to Settings > Video and Audio > Audio Format.
- Turn Change Format ON.
- Select either Dolby Digital 5.1 or Stereo and test if the sound works with WeatherNation.

4. Check Your Audio Connection Setup
- If you’re using an AV receiver or soundbar, verify that it supports the audio format you selected.
- Make sure HDMI or optical cables are securely connected.

If you have tried these already, let me know, and we can look into more advanced settings or other causes.

Does this sound good? Are you able to check these items now?
