iPhone 音频播放:强行通过内置扬声器? [英] iPhone audio playback: force through internal speaker?

问题描述

有谁知道是否可以实现即使插入耳机也可以通过内置扬声器播放音频文件?

Does anyone know if it is possible to implement playback of an audio file through the internal speaker even if the headphones are plugged in?

推荐答案

我不确定您的音频播放是如何进行的，但请尝试查看 音频会话编程指南

I'm not sure how you are doing your audio playback, but try having a look at the "Redirecting Output Audio" section of the Audio Session Programming Guide

看起来像这样:

UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;  // 1 
AudioSessionSetProperty ( 
    kAudioSessionProperty_OverrideAudioRoute,                         // 2 
    sizeof (audioRouteOverride),                                      // 3 
    &audioRouteOverride                                               // 4 
);
