YARP Microphone module should be deprecated

[barbalberto]

For audio capture / play sounds the standard module in yarp is the portAudio device, but there is another device called Microphone in yarp/src/module with Windows and Linux implementation.

The linux implementation uses /dev/dsp device which is deprecated and replaced by ALSA (used by portaudio).

If portaudio is working well in windows then I suggest to deprecate the microphone device.

@robotology/all-robotology-developers Is anyone using the microphone device or for some reason against deprecating it?

[barbalberto]

On a quick test with @randaz81, we saw that compilation of the module fails on Windows.

On Linux it uses a deprecated version of linux driver. Furthermore, when I tried to run it the only output was:

WARNING: the MicrophoneDeviceDriver is just a cartoon
WARNING: it hasn't really been written yet
/dev/dsp: No such file or directory

I'll go forward to deprecated it in favor of portaudio.
@drdanz @randaz81 do you agree?

Hi,

As far as I remember, there are some linux packets (aoss or alsa-oss ?) to get /dev/dsp (belonging to the deprecated
oss interface) emulated on alsa. This might be the way to get the non-cartoon ?

Anyway, the device driver used by our iCub already uses portaudio for the ear-microphones if I recall
correctly, so no problem here with bashing /dev/dsp.

Cheers,
Frederic
