USB Volume Unlocker

USB Volume Unlocker restores reliable, usable volume control for USB audio hardware on Android, addressing the common issue where USB-C dongles, DACs, and adapters play quieter than expected due to system-level limits. The app applies safe, standard Android audio adjustments so connected USB audio devices behave more predictably without root, firmware changes, or background services. It runs entirely on your device, requires a single tap to apply the change, and avoids ads, accounts, analytics, or network access—making it a compact, privacy-focused utility for anyone who uses external USB audio accessories.
