Воспроизведение звука NDI на симуляторе iOS великолепно, но iPad работает с ошибками и заикается. ⇐ IOS

[Anonymous]

Я пытаюсь реализовать аудиоприемник NDI на iOS. В симуляторе iOS звучит великолепно, но на iPad (iPad Air 2?) есть некоторые подтормаживания и сбои. Я почти уверен, что это связано с воспроизведением буфера, но не знаю, как это исправить или что не так.
