All of you propably already know that new iPad Pro has four speakers. When you listen to stereo audio and rotation the device, audio channels are automatically switched to correct speakers so that the user can hear it from correct eft and right side.
You may not know that when you use e.g. Skype, it also automatically does not play audio from the speaker which is located next to the microphone.
This is to reduce echo, becuase microphone and one of the speaker is located very close together.
It actually plays audio only on two speakers which are located on the opposite side of the device.
You can enable this "feature" when you configure Audio Unit as kAudioUnitSubType_VoiceProcessingIO subtype.
This works perfectly with this configuration but all audio processing features like "echo canceler" or "automatic gain control" are also enabled.
Do you know if there is a API which I can use to enable this particular behaviour for kAudioUnitSubType_RemoteIO subtype audio unit?
BTW: I know that there are properties to disable voice processing for kAudioUnitSubType_VoiceProcessingIO subtype, but I am looking posibility to enable this particular feature.
Thanks in advance.
