What can I do when the volume bar has disappeared and there’s no sound in apps on my device?

A factory reset can help, but consider it a last resort. It will erase all your data, so ensure backups:
1. Backup your data.
2. Head to ‘Settings’.
3. Select ‘System’ or ‘General Management’.
4. Tap ‘Reset’.
5. Go for ‘Factory data reset’.
6. Follow the on-screen instructions.

I once solved this issue by connecting to external hardware. When my phone had no sound and the volume bar vanished, I plugged in my external speakers. Sound worked through them. After disconnecting, the audio returned to normal on my device. Seems like it triggered an internal reset.

Check if there is any issue with recently installed apps or updates. Sometimes, new software can cause unexpected changes. Here’s what you can do:
1. Navigate to your device’s settings.
2. Select ‘Apps’ or ‘Applications’.
3. Check recent installs or updates.
4. Uninstall new apps or updates to see if the issue resolves.

Notification settings can sometimes be the culprit:
1. Open ‘Settings’.
2. Choose ‘Notifications’.
3. Look at individual app notifications.
4. Ensure volume notifications are enabled for all apps.

Detailed steps to follow:
1. Check for system updates: ‘Settings > System > Software Update’.
2. Boot into safe mode to see if a third-party app is causing the trouble:
– Hold the power button until options appear.
– Press and hold ‘Power off’ until ‘Reboot to safe mode’ appears.
– Tap ‘OK’.
3. If the problem resolves, uninstall recently added apps one by one.
4. If safe mode doesn’t help, a factory reset may be necessary. Backup all data before proceeding.

First, examine your device’s sound settings. It might seem basic, but it’s often the simplest solution that’s the most effective:
1. Open the ‘Settings’ menu.
2. Select ‘Sound’ or ‘Audio’.
3. Ensure media volume is up.
4. Confirm that ‘Do Not Disturb’ or ‘Silent Mode’ is off.

One effective method is to reset the app preferences:
1. Go to ‘Settings’.
2. Tap on ‘Apps’ or ‘Applications’.
3. Hit the three-dot menu or ‘More’ option.
4. Select ‘Reset app preferences’.
5. Confirm the action. This doesn’t delete any data but can fix the issue.

When all else fails, seek professional help. A minor internal hardware issue could be to blame. A technician found such a problem in my device. After a prompt repair, everything returned to normal. Professional guidance can sometimes quickly pinpoint the root cause.

Once, I barely noticed that my headphone jack was filled with dirt and lint. The sound and volume bar ceased functioning. I cleaned it out carefully with a soft brush, and everything was back to normal. It’s peculiar, but sometimes physical obstructions cause these problems.

This problem happened to me and performing a soft reset helped. You can do this by holding down the power button and the volume down button together until your device restarts. This quick step brought back the volume bar and sound in my apps.
