У вашего броузера проблема в совместимости с HTML5
Sony Xperia XZ2 Premium launched several weeks ago with a major camera glitch that sometimes doesn't record audio. After the first major update, the glitch is still there. It is impossible to know if the audio properly record until it is too late (the recording stops and you playback). This is a major glitch and I can't trust the phone to record videos until it is fixed.
