Xiaomi Redmi Note 9 – a popular smartphone with powerful hardware and flexible settings MIUI, But standard features don't allow you to install live wallpaper with built-in sound, and this capability requires workarounds, from third-party applications to fine-tuning system settings.

In this article, you’ll find 3 working ways to add animation from audio to the lock screen and home screen, including detailed instructions for selecting apps, optimizing performance, and solving typical problems. We'll also look at why sound can stutter or disappear, and how to avoid it without losing image quality. MIUI 12-14 and Android 10-12.
Why Redmi Note 9 doesn’t have live wallpaper with default sound
Smartphone manufacturers limit the functionality of live wallpaper for several reasons:
- 🔋 Energy consumption: animation + Background sound discharges the battery 15-25% faster (GSMArena 2023 test data).
- 📱 Performance: Helio processor G85 Redmi Note 9 is not optimized for permanent background animation, which can cause lags.
- 🛡️ Security: MIUI Blocks auto-run third-party applications to protect against malware.
- 🎨 Design concept: Xiaomi bets on minimalism in standard themes, offering live wallpaper only in premium series (Mi 13, Mix Fold).
But these limitations are bypassable, and the key is to understand that the sound in the live wallpaper is not implemented through system settings, but through third-party applications that mimic background playback, which means that:
