I'm doing some test work on android music playback. I have a headset and a bluetooth headset connect with the phone at the same time. Then there will be 4 output devices that can play the sound: speaker, handset, headset, and the BT_headset. What I want to know is: is there a way to switch the audio output to the 4 device using code? I cant do switch between speaker and handset if there is no headset plugin using audioManager.setMode(). But, if a headset plugin the sound can not out from handset. Then, if the headset and bt_headset connect at the same time, the sound always out from the later connect one.

  • When you say BT_headset, are you talking about SCO or A2DP? I.e. is it a headset intended for voice calls only, or is it also intended for media playback? – Michael Jul 29 '13 at 08:48
