我有索尼xperia sl，并有一个蓝牙耳机（sbh20）。当我连接它时，我可以从SBH20播放音乐，但如果我将另一个earpohone连接到手机的3.5 mm插孔，则来自蓝牙设备的音频被禁用。一次只有一件事，手机的3.5千斤顶或蓝牙设备。如果两者都同时发生，以便输出可以同时来自2个耳机。
I have Sony Xperia SL and have a bluetooth headset (SBH20). I can play music from SBH20 when I connect it but then if I connect another earpohone to my phone's 3.5 mm jack, the audio from bluetooth device gets disabled. Only one thing works at a time, either phone's 3.5 jack or bluetooth device. Is it possible if both works simultaneously so that output can come from 2 earphones at the same time.
I have tried doing the exact opposite thing (Forcing Audio to go through bluetooth instead of device speaker) so it definitifely is possible to play at least different audio through different streams (Media, Call, etc.) It set it inside of tasker to "Media" stream and it came out of my phone, so it might be possible to get it working. The app needs to support playing Audio through multiple streams. I don't know if there is an app for that that does split it up.
Sorry for posting it as a answer, my reputation isn't high enough yet to comment...
