Many users face a problem: even after turning on HD Audio in the settings, the sound remains bland, and in some applications (for example, Spotify or YouTube Music), high quality simply does not play. In this article, 3 proven ways to turn on HD Audio on the Poco X3 Pro, as well as solving typical errors: from a gray menu item to no effect after activation.

🔍 It's important: HD Audio only works with compatible headphones (with resistance from the headphones). 16 Ohms) or Bluetooth devices that support codec LDAC/aptX HD. Check the characteristics of your audio equipment before setting up!

1. Enable HD Audio through standard MIUI settings

The easiest way is to use built-in MIUI options, but it doesn't work on all firmware versions. If you have a Poco X3 Pro on MIUI 12.5+ or MIUI 13/14, follow the instructions:

📌 Path: Settings → Sound and vibration → Sound quality.

In this menu you will see two key parameters:

🎧 Wired headphones: High quality option (Hi-Res) Turn it on if compatible headphones are connected.
📶 Bluetooth: Audio codec. Select LDAC or HD (If your headphones support them).

⚠️

Note: If the Hi-Res option is gray and inactive, your firmware does not support HD Audio by default.

Check out the MIUI version (update if necessary)

Connect compatible headphones (wired or Bluetooth)

Close all audio applications before setting up

Reboot your smartphone after the changes-->

If standard settings do not allow HD Audio to be enabled, use a hidden menu of engineering options, which works on most versions of MIUI, but requires caution:

📌 Instructions:

Open the Phone app and enter the combination: ##36446337## (code for MIUI Hidden Settings).
Go to Hardware Testing → Audio → Headset Mode.
Find the Hi-Res output setting and set the Enabled value.
Save the settings and restart the device.

🔧 Additional parameters:

🔊 Headset volume – Increase to 150% for higher volume (caution: risk of distortion!).
🎛️ EQ settings – set the equalizer to your headphones.

⚠️

Warning: Changing settings in Hidden Settings may cause sound to crash.If wheezing or distortions occur after settings, reset the sound settings via Settings → Annexes → Application management → Settings (⚙️) → Reset.

What if the #36446337## code doesn't work?

On some firmware, Xiaomi blocks engineering codes. Alternative: 1. Install MIUI Hidden Settings from Google Play. 2. Grant it ADB rights (instruction in section 3). 3. Find the Hi-Res Audio option in the Audio section.

3. Enable HD Audio via ADB (for power users)

If previous methods fail, manual activation via Android Debug Bridge (ADB) is guaranteed to include HD Audio, but requires a PC and basic command line knowledge.

📌 Step-by-step instruction:

Get Poco on. X3 Pro to PC and type in the command line: adb shell settings put global hd_audio_enabled 1 adb shell settings put global force_hd_audio 1

🔍 Verification of the result:

⚠️

Note: Some of the updates after the update MIUI setting ADB To detect changes, use the command: adb shell cmd settings_secured put global hd_audio_enabled 1

4. HD Audio Problems on Poco X3 Pro and Their Solutions

Even after successful activation, users often encounter common errors, and here are the most common ways to fix them:

Problem.	Possible cause	Decision
The option of Hi-Res gray	Incompatible firmware or headphones	Update MIUI or use ADB
The sound is interrupted or wheezing	Too high volume in Hidden Settings	Reset the sound settings to standard
HD Audio only works in some applications.	The app does not support Hi-Res.	Use Poweramp or USB Audio Player PRO
After the reboot, HD Audio is turned off.	Resetting MIUI settings	Set your settings through ADB (see Section 3)

💡 Advice: If HD Audio doesn't work on Spotify or YouTube Music, so check the streaming settings in the app itself:

🔄 Go to Settings → Sound quality.
🎧 Select Very High (320 kbps) to download.
📱 Enable the option Automatic reproduction in high quality.

💡

To check if HD Audio really works, download a 96kHz test file (e.g., from here) and listen to it via Poweramp. The difference with normal sound will be noticeable on quality headphones.

5.The Best HD Audio Listening Apps on the Poco X3 Pro

The standard MIUI player doesn't always handle high-quality sound correctly. Here are the TOP-3 apps optimized for Hi-Res Audio:

📱 1. Poweramp (Google Play)

✅ Support DSD, FLAC, WAV 192 keto/24 bit.
✅ Built-in 10-band equalizer.
✅ Hi-Res output option in output settings.

🎵 2. USB Audio Player PRO (Google Play)

✅ Works with external DACs through USB OTG.
✅ Support MQA (for Tidal Masters).
✅ Bit output without resampling.

🔊 3. Neutron Music Player (Google Play)

✅ 32/64-bit-processing.
✅ Support for Parametric EQ and crossfeed.
✅ Direct option USB Audio to bypass Android restrictions.

⚠️

Note: When using USB Audio Player PRO with an external DAC (DragonFly, iFi), turn off the power saving for the application in Settings → Battery → Battery Optimization, otherwise the sound will be interrupted.

6 How to Check if HD Audio Really Works

Many users include settings, but are not sure if the sound has really gotten better. Here are 3 ways to check:

🔍 Method 1: Test tracks

🎼 Download test files with frequencies from 44.1 kHz to 192 kHz.
🎧 Listen to them through headphones with resistance from 32 ohms.
📊 The difference should be noticeable in the details of high frequencies (for example, the sound of plates or strings).

📊 Method 2: Spectrum Analyzer

📱 Install the Spectroid app (Google Play).
🎵 Turn on the 192kHz test track and look at the chart.
✅ If the spectrum extends to 22-24 kHz, HD Audio is working.

💻 Method 3: System Logs (for Advanced System Logs)

🔧 Connect your smartphone to your PC and type the command: adb logcat | grep -i "audio"
🔍 Look for lines with sample rate: 192000 or bit depth: 24.

Critical detail: On the Poco X3 Pro with MIUI 12.5 firmware and below, HD Audio can only work through wired headphones. Bluetooth requires an upgrade to MIUI 13+ or manual firmware custom ROM (such as Pixel Experience).

FAQ: Frequent questions on HD Audio on Poco X3 Pro

❓ Why not after the switch on HD Audio sound is quieter?

This is normal: Hi-Res Audio uses a wider dynamic range, so the average volume can go down. Increase the volume manually or adjust the equalizer in the player (for example, raise the frequencies of 100-500 Hz by 3-5 dB).

❓ Can I include? HD Audio on Bluetooth headphones?

Yes, but only if your headphones support codec. LDAC, aptX HD or AAC 256+ kbit/s. In Bluetooth settings, select the appropriate codec (see section 1). TWS HD Audio is not available.

❓ Will it be? HD Audio to work in games or YouTube?

No. Hi-Res Audio is only supported in specialized audio players (e.g. Poweramp), and in games and most streaming services (except Tidal and Apple Music), sound is limited to 48 kHz/16 bits.

❓ Can I include? HD Audio without root?

Yes, all of the methods described in this article (standard settings, Hidden Menu, ADB) work without root rights. However, some custom firmware (for example, LineageOS) may require unlocking the bootloader.

❓ Why After Updating MIUI HD Audio is missing?

Xiaomi sometimes resets audio settings on major updates.Repeat activation via ADB (section 3) The command is: adb shell settings put global. hd_audio_enabled 1 --user 0 If it doesn’t help, reset your sound settings (Settings). → Annexes → Settings (⚙️) → Reset).

💡

HD Audio on the Poco X3 Pro requires compatible headphones, proper firmware and often manual activation. If the sound hasn't improved, check: 1) Bluetooth codec, 2) bitrate in the player, 3) settings in Hidden Menu.
