          Хороший звук с выводом без искажений видимо окончательно остался в Android 7. Ни в восьмом, ни в девятом звука без искажений нет.

          Комментарий к профессиональному отчету Xiaomi Mi A1 Stellio OpenSL On
          У Stellio можно видеть короткую импульсную характеристику от ресемплирования. Это дает более ранний пологий завал АЧХ и соответсвенно более "мягкий" звук.

          А по USB звук не испортился?
