I’m trying to use audio_output.cpp to play the audio from Pi headphone jack. (I use Matrix Creator)
The command I use:
./audio_output --raw_file=mic_16000_s16le_channel_8.raw --output=H --volumen=100 --sampling_frequency=16000
The raw_file comes from the output of ./micarray_recorder_direct.
But there nothing happens. What should we expect from this audio_output file?
to test the headphone jack, it can play sound normally.
