Disable audio enhancements for the active output device first; if playback is still slow despite the application showing 1.0×, test another default audio format and then repair the audio driver.
1. Disable audio enhancements
Windows 11
- Open Start → Settings → System → Sound.
- Under Output, select the speakers or headphones currently in use.
- Set Audio enhancements to Off.
- Close and reopen the music application, then test playback.
Windows 10
- Right-click the taskbar Volume icon and select Sounds.
- Open Playback.
- Select the active device and choose Properties.
- Open Enhancements, select Disable all enhancements, and click OK.
- Test playback again.
Enhancements can alter audio processing and cause playback-quality problems.^1^
2. Test a different default audio format
- Open the active playback device’s properties:
- Windows 11: Settings → System → Sound → More sound settings → Playback.
- Windows 10: Right-click Volume → Sounds → Playback.
- Select the device, choose Properties, and open Advanced.
- Note the current Default format so it can be restored.
- Select a different supported format, click Apply, and test the music.
- If necessary, test another available format.
For example, Windows may offer 2 channel, 16 bit, 44100 Hz (CD Quality), although the available choices depend on the device.^2^
3. Determine whether it is application-specific
Play the same file in a different music application.
- Normal in another application: reset or repair the original application, because its playback control or audio processing is the likely scope of the problem.
- Slow in every application: continue with the Windows audio steps below.
- Slow only through one headset or speaker: test the built-in speakers or another output device. This isolates the affected audio device.
4. Restart the Windows audio services
- Select Start, type services.msc, and press Enter.
- Right-click Windows Audio and select Restart.
- Right-click Windows Audio Endpoint Builder and select Restart.
- Reopen the music application and test playback.^3^
5. Update or reinstall the audio driver
- Search for and open Device Manager.
- Expand Sound, video and game controllers.
- Right-click the audio device and select Update driver.
- Restart Windows and test.
- If the problem remains, return to Device Manager, uninstall the audio device, and restart Windows so the driver is reinstalled. If needed, install the latest device-specific driver supplied by the PC or audio-device manufacturer.^1^
Also install pending Windows updates. On Windows 11, use Settings → Windows Update → Check for updates; on Windows 10, use Settings → Update & Security → Windows Update.^4^
If this is Windows 10, note that Microsoft support ended on October 14, 2025.^4^
