How to route to speaker

edited May 2013


I just use sample with PlayThroughChannel, when I plug my headphone in, it work fine.
But right after I unplug my headphone, then it will fail ( a strange, loud sound will be played instead of my voice).

Here is log:

Should I set any other config to route to speaker ?



  • Hi @zkidkid - it sounds like something's off with your audio system. Have you tried rebooting your device?

  • Hi Michael,
    I have rebooted many time. And I have tried with other application and it work well.
    I have tried to run example (AEAudioPlayThroughChannel) and it also not work with speaker.
