Vocore2 onboard microphone not recording
Posted: Mon Jun 19, 2017 2:53 pm
Hello,
I have a vocore2 + dock and i'm trying to record sound through onboard mic with the command;
ffmpeg -f alsa -ac 2 -ar 44100 -i hw:0 -t 30 /tmp/out.wav
But the out.wav file in tmp folder has no sound, not even noise. Also inspecting its waveform, it has zero amplitude throughout 30 seconds.
I have upgraded to latest firmware. What else could be the reason of this problem?
Thanks
