Watching a movie on Netflix app, left stereo audio suddenly diminishes noticeably. Problem persists after closing Netflix and opening iTunes and other apps. General>Reset>Reset All Settings corrects problem temporarily: stereo audio works properly. Problem recurs after watching movie on Netflix app for about 30 minutes. I have duplicated this malfunction 4 times, it is clearly not hardware related. Seems as long as I avoid the Netflix app audio works fine. Is this a Netflix problem or an iOS 7 issue? If Netflix is causing the malfunction, why does it persist even after closing Netflix and opening iTunes?
