[Nexus 5 Android Development] disiz:
Thanks for your answer. So I don't have such file in the phone, but I don't have any message after entering your logcat command on terminal emulator, and on my Nexus 6 with Android 6 I have this file, but no message too after your command...

And then I just want to tell you again I have android 4.4. so I'm not sure this Android version have this audio_platform.xml file.

To be clear, what do I have to look for on the system xml files ? This message ? SND_DEVICE_IN_CAMCORDER_MIC ? I have this on audio.effects.conf, might be usefull ?

# Audio preprocessor configurations.
# The pre processor configuration consists in a list of elements each describing
# pre processor settings for a given input source. Valid input source names are:
# "mic", "camcorder", "voice_recognition", "voice_communication"
# Each input source element contains a list of effects elements. The name of the effect
# element must be the name of one of the effects in the "effects" list of the file.
# Each effect element may optionally contain a list of parameters and their
# default value to apply when the pre processor effect is created.
# A parameter is defined by a "param" element and a "value" element. Each of these elements
# consists in one or more elements specifying a type followed by a value.
# The types defined are: "int", "short", "float", "bool" and "string"
# When both "param" and "value" are a single int, a simple form is allowed where just
# the param and value pair is present in the parameter description

Do you see something interesting in here ?

Thanks a lot for your help, and I'm very surprised that it's so hard to set another input audio of our choise for all apps :eek:
