Quick Checks
Try these first before diving into specific issues. Order matters.
- 1Enable an audio effect in Echo Equalizer first — turn on Equalizer, Bass Boost, or Virtualizer.
- 2Force-stop and relaunch your music app, then start playback.
- 3Return to Echo Equalizer and toggle effects to A/B test.
- 4If not connected, Echo automatically tries to attach to the Global Audio Mix.
- 5New to equalizers or effects? Check the basics in Issue #2 below.
- Use Spotify or YouTube Music for best results.
- Check compatibility via the Supported & Unsupported Music Players list.
- Open Echo Equalizer and enable an effect (Equalizer, Bass Boost, or Virtualizer).
- Force-stop your music app, reopen it, and start playback.
- Return to Echo Equalizer and confirm your player shows "Connected".
- If unconnected, enable Global/Legacy processing manually and reboot your device.
- Check for conflicting audio apps and disable them.
- Equalizer: Adjust frequency bands for bass/mids/treble balance.
- Bass Boost: Adds low-end weight. Too much can cause clipping.
- Virtualizer/3D: Widens stereo image. Subtle settings work best.
- Loudness/Output Gain: Overall volume shaping. Keep meters out of red.
- Read the User Guide for plain-language explanations and examples.
- In Echo Equalizer Settings, tap "Disable Battery Optimization".
- Allow the system prompt when it appears.
- Follow device-specific steps at dontkillmyapp.com for your phone brand.
- Reboot your device after making these changes.
- Lower Bass Boost or any high frequency boosts.
- Reduce Output Gain slightly.
- Enable the Limiter if available.
- In Settings, increase Processing time to give the audio more headroom.
- Note: Higher Processing time adds latency, which may cause lip-sync issues in video.
- Keep sliders within about ±6 dB — avoid extreme boosts or cuts.
- Adjust Output Gain to taste.
- Enable the Limiter and keep meters out of red.
- Common conflicts: Sound Assistant (Samsung), AudioFX (LineageOS/custom ROMs), and other equalizer or sound-enhancer apps.
- Disable, uninstall, or freeze any conflicting audio apps.
- Reboot your device after removing conflicts.
