Why are different volume levels and sound effects noticed when switching Apps on the Xiaomi 17 Ultra?

If there are different volume levels and sound effects when switching between different Apps on the Xiaomi 17 Ultra, please refer to the following explanation:
1. Different Apps use independent audio processing engines and sound parameter configurations. As a result, volume output, equalization, and sound effects can vary from one App to another.
2. Media players, games, and video platforms can apply distinct dynamic range control or enhancement algorithms, leading to slight differences in listening experience.
3. The system automatically adapts to each App’s audio profile, which can create a perceptible transition when switching.
4. The device undergoes strict acoustic calibration and testing before leaving the factory to ensure consistent hardware performance.
5. This variation is related to software sound processing differences rather than a hardware issue. Please feel confident in using your device.
