Hi Langtian
We're not sure what exactly is going on. Could you file a bug report
and attach some code we could use to reproduce the problem?
Thanks
Bill

Subject: Bluetooth one way audio with iPhone OS 3.1
I have play_and_record audio session, it works well with build in
speaker & microphone.
I enabled
kAudioSessionProperty_OverrideCategoryEnableBluetoothInput to
support
bluetooth audio.
If I start the audio session (audioqueue) with
kAudioSessionProperty_OverrideCategoryEnableBluetoothInput
enabled directly, it also works on both bluetooth input and
bluetooth output.
However, if during the session, I enable the audio route to
speaker for a few seconds (either with
kAudioSessionProperty_OverrideCategoryEnableBluetoothInput
enabled or not), then I disable the
route to speaker, set
kAudioSessionProperty_OverrideCategoryEnableBluetoothInput again, I
only get bluetooth input/MIC, but I can't hear anything on the
bluetooth speaker. I checked the audio
queue, which is working. (It has the interrupt yo get data)
I verified all the audio hardware information, like route is
Bluetooth, sample rate is 8000, category is play-and_recorder,
actually they all same as the previous working one.
Any one see this issue? Is this a iPhone OS bug? Or where is my
problem?
Thanks,
Langtian
