How to Fix No Sound During Calls on Xiaomi Redmi Note 7 Pro

Troubleshooting Call Sound Issues on Redmi Note 7 Pro

• 💡 Check call volume during an active call using the side buttons, ensuring it's not set to zero.
• 📌 You can also access and adjust the specific call volume slider within the in-call menu.

Connectivity and Earpiece Checks

• 🎧 Disconnect Bluetooth devices to rule out accidental connections to earbuds or other audio output devices.
• 🧼 Gently clean the earpiece with a soft brush to remove any debris that might be obstructing sound.

Software and Settings Adjustments

• 📞 Test sound in other apps like WhatsApp by making a call to determine if the issue is with the phone's default calling app or a broader system problem.
• ⚙️ Navigate to Settings > Connections & Sharing > Reset Wi-Fi, mobile networks, and Bluetooth, then tap Reset settings to resolve potential network configuration conflicts.
• 🔇 Ensure your device is not in silent mode, as this can also cause a lack of sound during calls.

Device Restart

• 🔄 Perform a device restart (not a factory reset) by holding the power button and selecting 'Reboot' to refresh the system and potentially resolve temporary glitches.
• 🚀 After the reboot, your device will be ready to use with sound restored during calls.
