I now believe other apps might be using Qualcomm audio with CAF. See audio_extn_utils_send_audio_calibration at https://github.com/dtsinc/DTS-Eagle-Integration_CAF-Android-hardware-qcom-audio/blob/master/hal/audio_extn/utils.c
and voice_get_incall_rec_snd_device at https://github.com/dtsinc/DTS-Eagle-Integration_CAF-Android-hardware-qcom-audio/blob/master/hal/voice.c I have no C/++ knowledge. How can I find out if I can call these methods from native side? Since other apps can, there must be a way. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
