Redmi 5A Ringer Speaker Not Working Comprehensive
Troubleshooting & Fixes

If your Redmi 5A stops ringing or the loudspeaker fails, do not panic. This is one of the most frequent issues for many Redmi users. It may occur due to a variety of different reasons, both minor, such as speaker malfunction, to more serious ones located on the motherboard of the phone. The positive thing is, this problem can be eliminated in the majority of cases by a couple of simple checks and some minor repair work.

Common Causes of Redmi 5A Ringer Speaker Issues

Understanding the root cause of your Redmi 5A’s speaker problem is the first step towards a solution. Here are the most common reasons why your ringer speaker might not be working:

• Software Glitches: Minor software bugs can often disrupt speaker functionality. A simple restart or a software update can frequently resolve these issues.
• Dust and Debris: Over time, the speaker grille can accumulate dust, lint, and other debris, blocking sound output. Regular cleaning is crucial for prevention.
• Water Damage: Accidental exposure to water can severely damage internal components, including the ringer speaker. Immediate action is necessary if your phone has been exposed to moisture.
• Physical Damage: Dropping your phone or other physical impacts can damage the speaker itself or its internal connections.
• Incorrect Settings: The volume might be inadvertently turned down, or the phone could be in silent or Do Not Disturb mode.
• App Conflicts: Occasionally, certain third-party applications can interfere with the speaker’s normal operation.

Step-by-Step Troubleshooting for Redmi 5A Speaker Problems

Follow these steps to diagnose and resolve your Redmi 5A ringer speaker issues:

Step 1: Check the Speaker Itself

The first thing you should check is whether the speaker hardware is working or not.

• Open the back cover of the phone.
• Locate the loudspeaker unit – this is the small box-shaped component at the bottom of the phone.
• Replace it with a working speaker and test again.
• If sound comes through with the new speaker, then the old speaker is faulty. Just replace it, and your problem is solved.

However, if there’s no sound even after replacing the speaker, then the issue is likely on the mainboard or chip level.

Step 2: Test the Speaker with a Multimeter

To check whether the speaker is fine:

• Use a multimeter to check the speaker's resistance.
• A normal speaker will beep on both sides when tested.
• The resistance should be around 8 to 12 ohms.
• If it shows values in this range, the speaker is okay.

Step 3: Check the Speaker Connection Points on the Motherboard

Once the speaker is confirmed to be working:

• Look at the two contact points where the speaker touches the motherboard.
• Use a multimeter in diode mode.
• Place the red probe on the ground and use the black probe to check both contact points.
• You should get similar readings on both points, around 395–396.

If both values are the same, your audio track is fine. But if the values are missing or unequal, your track is open or broken.

Step 4: Trace the Speaker Line

If the track is faulty:

• Start tracing the supply line from the speaker connector.
• The supply comes from the jack connector and goes to the main motherboard.
• There is a flex cable or strip that connects these parts.
• Make sure the supply is properly coming through the strip to the speaker area.

The speaker supply line is shared with charging, microphone, and other components, so check these too.

Step 5: Check the Components in the Speaker Circuit

In the loudspeaker section, several components control the sound output. These include:

• Coils
• Diodes
• Capacitors
• Resistors
• Filters
• And finally, the Ringer IC

Here’s how they work:

• The speaker connector is linked to coils, which are then connected to a ringer IC.
• These coils and components are parallel in the circuit.
• If any of these parts are damaged, the speaker may not work.

Step 6: Test or Replace the Ringer IC

The Ringer IC (Integrated Circuit) is responsible for sending sound signals to the speaker.

• It is a Ball-type chip (i.e., it is connected through little balls of solder).
• In case the Ringer IC is faulty or disconnected, the speaker circuit will fail.
• It will be possible to replace the Ringer IC; otherwise, a jumper method can be used to bypass the Ringer IC.

If the ringer speaker functions correctly in Safe Mode, an app is likely the culprit. Uninstall recently installed apps one by one until the issue is resolved. For more general Phone Troubleshooting tips, refer to our comprehensive guides.

Step 7: Use Jumper Wires to Bypass Faulty Lines

If any track or component is broken, you can use jumper wires to restore the connection.

• Identify the two points from the speaker connector that go to the Ringer IC.
• Place one jumper from the first pin of the speaker connector to the IC.
• Place the second jumper from the other pin of the speaker connector to the second point on the IC.

This will bypass the faulty tracks and directly connect the speaker to the output.

Step 8: Final Testing

After all these repairs:

• Connect the speaker to the phone again and switch the phone on.
• Use a ringtone or music to check whether the speaker is working.
• When the sound is out, you are through.

For such complex hardware repairs, it is highly recommended to seek professional help from a certified technician. Remember to prioritize Mobile Repair Safety when dealing with internal components.

Additional Tips:

• You should always ensure that your testing tools are in place.
• An original or superior quality replacement parts give the best.
• As long as you are not sure about taking care of small motherboard components, the best way is to seek the assistance of a mobile repair technician.

Prevention Tips for Redmi 5A Speaker Issues

If you want to keep your Redmi 5A’s speaker and ringer functioning smoothly, then here are some detailed prevention tips that you can take. These tips will also help you to extend the lifespan of your device.

• To protect the speaker grille from dust & debris, use a phone case. Make sure to clean it regularly and avoid a dusty environment.
• To prevent moisture & liquid damage, avoid water exposure, and do not use in the bathroom. Keep silica gel packets for emergencies.
• To avoid software conflicts, disable unnecessary sound mods, update MIUI regularly and uninstall suspicious apps.
• To prevent physical damage, do not drop the phone and use a shockproof case.
• Avoid using your phone at maximum volume for extended periods, use the equaliser wisely, and try to keep the battery above 20% to prevent strain on components. For issues like Phone Overheating, proper usage habits are key.
