USB Volume Unlocker

USB Volume Unlocker helps restore consistent, usable volume control for USB audio devices on Android.

Some USB-C dongles, DACs, and adapters may play audio at a lower volume than expected due to system-level limitations. This app applies safe system audio adjustments so your connected USB audio hardware behaves more predictably.

No rooting. No ads. No tracking. Just works.
