Hello,
I'm sorry to hear about the trouble you're experiencing with your iPhone's audio controls while streaming videos. This seems like a frustrating problem, but I'm confident we can find a solution.
Following are a few steps to try:
1. **Restart Your Device**: As has already been suggested, a simple restart can sometimes fix a multitude of issues. Here's how you can do it - press and hold either volume button along with the side button until you see the power-off slider. Drag the slider to turn off, and then hold the side button to turn it back on after 30 seconds.
2. **Check for Software Updates**: An outdated version of iOS might cause unexpected issues. To check if you're on the latest version, go to Settings > General > Software Update.
3. **Isolate the Issue**: Identifying when the issue occurs can help narrow down its source. Does it only happen when using certain apps like YouTube or Disney+? Does the issue persist if you switch from WiFi to cellular data, or vice versa? If the video is downloaded onto your iPhone, do you still experience these issues?
4. **Check Audio Output**: Even though your headphones are off, your iPhone might still be trying to connect to them. Go to Control Center (swipe down from the upper-right corner on iPhone X or newer, or swipe up on iPhone 8 or older), and check where the audio is being directed. You should see a small icon at the top right of the music control box that indicates where the sound is being output. Ensure it's set to your iPhone.
5. **Reset All Settings**: If the issue persists, consider resetting your iPhone's settings. It won't erase your data, but it will reset all settings to their defaults. Go to Settings > General > Reset > Reset All Settings.
If you continue to have trouble after trying these steps, it might be time to reach out to Apple Support directly for more help.
Remember to back up your device regularly, especially before performing operations like Reset All Settings. I hope these suggestions are helpful!
