Hello!I am working on an app that plays audio and accepts voice commands simultaniously. When I play audio through bluetooth in my car, the Audio Session for the app uses the Bluetooth HFP ports. This causes the output audio quality to become very poor. If I switch to AVAudioSessionPlayback, the output is on the A2DP port, which sounds great. Ideally I would like to be able to play ouput through A2DP, and accept input through HFP, but I assume this is a limitation of bluetooth, or everything would already work this way to improve sound quality. For my app it would be acceptable to accept input from the phone's microphone, and play the audio through bluetooth, but this also seems impossible as described here: http://stackoverflow.com/questions/22146406/ios-input-mic-output-bluetooth-device. Any advice on improving playback audio quality when connected to bluetooth while using AVAudioSessionPlayback and record would be greatly appreciated. Has anyone encounted this issue before and had a suitable fix?Thanks!
