Xiaomi Sound Not Working After HyperOS Update

Xiaomi Sound Not Working After HyperOS Update – UK Fix

If your Xiaomi, Redmi, or POCO device has lost all sound after a HyperOS update—no ringtone, no media audio, no notification sounds—this guide helps you diagnose and fix the issue. Although this guide focuses on HyperOS, many of the same troubleshooting steps also apply to devices running recent MIUI versions.

Quick Answer:
If sound stopped working after a HyperOS update, first check your volume settings, Do Not Disturb, and Bluetooth connections. Restart your phone and check for available updates. Some HyperOS releases have introduced audio issues on specific Xiaomi, Redmi and POCO models—a software issue introduced by a recent update may be the cause. If other users report the same behaviour on the same software version, check for a newer OTA update before assuming the speaker is faulty.

Section 1 – Quick Checks (Always Try First)

Many sound issues after updates are caused by simple settings changes, not hardware failure.

Try these in order:

  1. Check media volume – Press the volume button and tap the three dots (⋮) to expand volume controls. Ensure Media volume is turned up, not just ringtone volume.
  2. Check Do Not Disturb – Swipe down the notification shade. If the DND icon is highlighted, tap it to turn OFF.
  3. Check silent mode – Ensure the phone is not in Silent or Mute mode.
  4. Disconnect Bluetooth – Disconnect any connected Bluetooth devices, then test the phone speaker again.
  5. Restart your phone – A full reboot can resolve temporary audio service glitches.
  6. Check for system updates – Settings → About phone → System update. If Xiaomi has released a patch for a known audio bug, it will appear here.

Section 2 – Known Software Issues Affecting Some HyperOS Builds

Some HyperOS releases have introduced audio issues on specific Xiaomi, Redmi and POCO models. If your problem started immediately after installing a new update and other users report the same behaviour on the same software version, check for a newer OTA update before assuming the speaker is faulty.

Confirmed affected devices (examples):

  • Redmi Note 13 – No sound output on certain builds. Awaiting an official software update.
  • POCO F7 / POCO X7 Pro – Poor Dolby audio quality. Awaiting an official software update.
  • Redmi Pad 2 – Complete loss of speaker audio. Awaiting an official software update.

What to do:

  • Check your device model – Settings → About phone → Model name.
  • Check your HyperOS version – Settings → About phone → HyperOS version.
  • If your device is affected – Wait for the official OTA update. Xiaomi is working on software fixes for affected builds.
  • Do NOT factory reset – For confirmed system-level bugs, a factory reset is unlikely to resolve the issue. Try the troubleshooting steps and check for a newer update first.

Temporary workarounds (varies by bug):

  • Use headphones (works for some models).
  • Toggle Dolby Atmos on/off (works for some Dolby audio issues).

Section 3 – Audio Service Glitch (Temporary)

If sound works after a restart but stops later, the audio service may have crashed.

Try these in order:

  1. Restart your phone – A simple reboot often resolves audio service glitches.
  2. Clear system cache – If available on your device, boot into Recovery Mode and clear the cache partition. The exact steps vary by Xiaomi model.
  3. Check for app-specific issues – If only one app has no sound, clear the app's cache: Settings → Apps → Manage apps → select the app → Storage → Clear cache.
  4. Boot into Safe Mode – If audio works normally in Safe Mode, a recently installed third-party app is likely interfering with playback or audio processing.

Section 4 – Bluetooth Audio Conflict

If sound is playing but you can't hear it, check that audio isn't being routed to a Bluetooth device.

Try these in order:

  1. Disconnect Bluetooth – Settings → Bluetooth → disconnect any connected devices. Also check that audio isn't being routed to another nearby Bluetooth device, such as a smartwatch, car stereo or wireless speaker.
  2. Check media output – Swipe down to open Control Centre and check the media output selector. Ensure audio is sent to the phone speaker, not a Bluetooth device.
  3. Restart your phone – After disconnecting Bluetooth, restart to reset audio routing.

Section 5 – Speaker Hardware Test

If none of the above work, test whether the speaker hardware is functioning correctly. Consider hardware failure only after software settings, Bluetooth routing and recent updates have been ruled out.

Try this:

  1. Hardware test (if supported) – On many Xiaomi devices, open the Phone app and dial *#*#64663#*#* to access the hardware test menu. Select Speaker from the test menu to play test tones. If nothing happens, your model may not support this code.
  2. Test headphones – Plug in wired headphones or connect Bluetooth headphones. If sound works through headphones but not the speaker, the issue is with the speaker itself or a known bug affecting speakers.
  3. If the speaker test produces no sound – Contact Xiaomi Support or an authorised repair centre.

Why Did Sound Stop Working After HyperOS Update?

  • Software issue introduced by a recent update – Some HyperOS releases have introduced audio issues on specific devices. Xiaomi is working on fixes.
  • Settings reset – Updates can reset volume, Do Not Disturb, or silent mode settings.
  • Bluetooth conflict – Audio may be routing to a connected Bluetooth device.
  • Audio service glitch – Temporary software issues can affect the audio system.
  • Speaker hardware failure – Consider this only after software settings, Bluetooth routing and recent updates have been ruled out.

⚠️ What NOT to Do

  • Don't factory reset for a known bug – For confirmed system-level bugs, a factory reset is unlikely to resolve the issue.
  • Don't assume hardware is faulty – Check for known bugs first.
  • Don't force updates – Wait for official OTA patches to avoid causing additional issues.

Quick Questions

Why did my Xiaomi sound stop working after HyperOS update?

Confirmed affected devices include Redmi Note 13, POCO F7, POCO X7 Pro, and Redmi Pad 2.

Xiaomi Equalizer Settings: Best Sound for Headphones & Earbuds (UK 2026)

How to Boost Headphone Bass on Xiaomi Phones (MIUI Guide for UK Users) Music is closely tied to emotions, and for many UK users, headphones are a constant companion throughout the day—whether commuting in London , relaxing in a Manchester flat, or catching up on podcasts in Birmingham . Naturally, everyone wants the best possible sound quality from their Xiaomi device, without relying on third-party apps that take up storage space. Why Bass Matters Before boosting headphone bass, it’s worth understanding the basics. Humans can hear frequencies from 20Hz to 20kHz. The lower end, below 250Hz, represents bass sounds. Within this range, the lowest frequencies contribute to deep bass, while slightly higher frequencies provide “punchy” bass. MIUI’s equaliser allows you to tweak these frequencies, regardless of the headphone model—be it Mi AirDots , Redmi AirDots S, or higher-end wired headphones. Setting up the equaliser properly is crucial for achieving the richest sound experience...
