Xiaomi Sound Quality Worse After Update

Xiaomi Sound Quality Worse After Update – UK Fix

If your Xiaomi, Redmi, or POCO device started sounding worse after a system update—tinny, muffled, distorted, or lacking bass—this guide explains why it happened and how to fix it.

Quick Answer:
If sound quality dropped after an update, first check that your settings haven't been reset. Updates can affect Dolby Atmos, Bluetooth codecs, equalizer settings, accessibility audio, media output routing, Bluetooth profiles, app permissions, or audio effects. Try toggling Dolby Atmos off temporarily: Settings → Sound & vibration → Dolby Atmos → toggle OFF. Restart your phone. If the issue is a known bug, a system patch may be coming—check for updates regularly.

Section 1 – Check Dolby Atmos

Dolby Atmos enhancements can clash with audio output after updates. Some devices sound better with it on, others with it off.

Try this first:

  1. Toggle Dolby Atmos – Settings → Sound & vibration → Dolby Atmos → toggle OFF and compare the sound.
  2. Test different Dolby presets – If your device has presets (Music, Video, Voice, Game), try each one.
  3. Re-enable if needed – Some headphones sound better with Dolby Atmos enabled, while others may sound more natural with it disabled.

Section 2 – Check Bluetooth Codec (If Bluetooth Audio Is Affected)

If the issue only affects Bluetooth headphones, updates can reset codec settings.

Try these in order:

  1. Check Bluetooth audio codec – Settings → Additional settings → Developer options → Bluetooth audio codec → ensure the phone is using the highest-quality codec supported by both your phone and your headphones.
  2. Test different codecs – Try switching to AAC or SBC to see if quality improves.
  3. Re-pair the headphones – Forget the device and pair it again.

Section 3 – Check Equalizer and Sound Settings

Updates can reset your equalizer settings or change sound profiles.

Try these in order:

  1. Check the equalizer – Settings → Sound & vibration → Sound effects → Graphic equalizer (if available on your device).
  2. Reset sound settings – Settings → Sound & vibration → Sound effects → Reset to default (if available).
  3. Check sound modes – Some devices have "Sound enhancement" or "Mi Sound" options. Try different presets.

Section 4 – Check Accessibility Audio Settings

Updates can sometimes change Accessibility audio settings, which can affect sound quality.

Check these:

  1. Mono audio – Settings → Accessibility → Hearing → Mono audio. If enabled, try disabling it.
  2. Audio balance – Settings → Accessibility → Hearing → Audio balance. Ensure it's centred (not shifted left or right).

Section 5 – Restart and Check for Updates

A simple restart can resolve temporary audio glitches. Also check if a follow-up patch has been released.

Try these in order:

  1. Restart your phone – A full reboot can refresh audio services.
  2. Check for system updates – Settings → About phone → System update. Some HyperOS versions have had temporary audio issues, and follow-up patches may have been released.
  3. Check Bluetooth codec – Section 2.

Section 6 – Test in Safe Mode (If Supported)

If the problem started after updating an app rather than HyperOS itself, testing in Safe Mode can rule out third-party audio enhancements.

How to boot into Safe Mode: The exact steps vary by Xiaomi model and HyperOS version. If Safe Mode is available, test whether the audio issue still occurs. If it disappears, a third-party app may be interfering with audio.

Hardware Reassurance

If the built-in speaker sounds distorted but Bluetooth and wired headphones sound normal, the speaker or its amplifier may have developed a hardware fault rather than the software update being the cause.

Why Did Sound Quality Get Worse After the Update?

  • Dolby Atmos clash – Built-in audio enhancements can interfere with headphone output on some devices.
  • Reset sound settings – Updates can reset equalizer or sound profiles.
  • Bluetooth codec reset – Updates can change codec settings.
  • Bluetooth profiles – Profiles may have been reset.
  • Accessibility audio settings – Mono audio or balance may have changed.
  • App permissions – Audio-related permissions may have changed.
  • Known bug – Some HyperOS versions have had temporary audio issues; check for follow-up patches.

⚠️ What NOT to Do

  • Don't factory reset your phone – This is rarely needed for post-update audio issues.
  • Don't assume the hardware is faulty – Check settings and codecs first.
  • Don't force LDAC or aptX HD – Only switch codecs if your headphones support them.
